The Intimate Wellness Glossary

The world of intimate wellness has its own vocabulary. Some terms come from medical literature, some from community culture, some from product specifications. All of them deserve clear, honest definitions — without clinical detachment and without unnecessary judgment.

This glossary covers 40+ terms you're likely to encounter while exploring products, reading research, or having conversations about sexual wellness. Bookmark it, share it, return to it whenever you need it.

A

Aftercare

The intentional process of emotional and physical reconnection that follows an intimate or sexual experience, particularly one that was intense or involved power dynamics. Aftercare might look like holding, talking, eating a snack, applying lotion, or simply being present with a partner. It acknowledges that experiences that bring you out of your everyday headspace benefit from a gentle re-entry. Aftercare is a sign of communication, not complication.

Anal play

Sexual stimulation involving the anal region, which contains a high concentration of nerve endings. Anal play ranges from external touch to penetration with fingers or toys specifically designed with a flared base — that base is non-negotiable for safety, as the anal canal does not self-stop the way the vaginal canal does. Lubrication is always recommended, as the anal canal does not self-lubricate. Go slowly, communicate, and prioritize comfort.

Arousal

The physiological and psychological state of sexual excitement. Physical arousal involves increased blood flow to the genitals, vaginal lubrication, erection of the clitoris or penis, and heightened sensitivity to touch. Psychological arousal is the mental component — desire, interest, anticipation. The two don't always sync up, and that's normal. Understanding the difference between physical readiness and genuine desire is an important part of self-awareness and communication.

B

Body-safe

A shorthand term for intimate products made from materials that are non-porous, non-reactive, hypoallergenic, and free from chemicals known to harm the body. Body-safe materials include medical-grade silicone, borosilicate glass, stainless steel, and ABS plastic. The term is not regulated, which means any brand can claim it — which is why knowing the specific material matters more than the label itself. See our [Material Safety Guide](/blogs/news/material-safety-guide) for the full breakdown.

Bondage

A consensual practice in which one partner is physically restrained — with rope, cuffs, ties, or other implements — as part of sexual or intimate play. Bondage is part of the broader BDSM spectrum and, like all kink practices, depends entirely on informed, enthusiastic consent from all parties. A safe word should always be established. When using physical restraints, check circulation and ensure the restrained partner can communicate clearly throughout.

Bullet vibrator

A small, compact vibrator typically shaped like a cylinder or rounded oval, designed for targeted external stimulation — most commonly of the clitoris or other erogenous zones. Bullets are discreet, often the most affordable vibrator option, and excellent for people new to vibration. Many couples incorporate bullet vibrators into partnered play for added stimulation. Browse the [DD Intimates vibrators collection](/collections/vibrators) for options.

---

C

Clitoral stimulation

Direct or indirect stimulation of the clitoris — the primary organ of female sexual pleasure. The external portion of the clitoris (the visible nub beneath the clitoral hood) is only a fraction of the full structure, which extends internally in a wishbone shape around the vaginal canal. Research published since the late 1990s has substantially revised understanding of clitoral anatomy. Most people with a vulva require clitoral stimulation to reach orgasm — penetration alone is not sufficient for the majority.

Cock ring

A ring worn at the base of the penis, or around the penis and scrotum, designed to restrict blood flow and help maintain erections. Many cock rings also include vibrating elements for partner stimulation. Cock rings should be used for no more than 20-30 minutes at a time and should never be so tight they cause pain or numbness. Stretchy silicone rings are the most accessible option for beginners.

Consent

The freely given, reversible, informed, enthusiastic, and specific agreement to engage in an activity. Consent is ongoing — it applies to each activity and each encounter, not to an entire relationship. Silence is not consent. Reluctant agreement under pressure is not consent. Consent can be withdrawn at any point. Building a shared vocabulary for consent — including how to say yes, how to say not yet, and how to stop — is one of the most foundational skills in sexual wellness.

---

D

Dildo

A non-vibrating penetrative toy designed for vaginal or anal use. Dildos vary widely in size, shape, material, and design — from realistic to abstract. The best dildos are made from non-porous materials like medical-grade silicone, borosilicate glass, or stainless steel. Any dildo intended for anal use must have a flared base. Browse [DD Intimates glass products](/collections/glass-dildos) for curated, body-safe options.

Discreet shipping

A packaging and billing practice that protects the privacy of customers ordering intimate products. DD Intimates ships orders in unmarked, plain packaging with no external indication of the contents, and billing appears under a neutral business name. Your purchase is yours.

---

E

Erogenous zones

Areas of the body with heightened sensitivity to touch, temperature, or pressure that can contribute to sexual arousal. Primary erogenous zones include the genitals, breasts, and inner thighs. Secondary zones vary widely by individual and can include the neck, ears, lower back, feet, scalp, and wrists. The map is deeply personal — part of sexual discovery is learning which areas of your own body (or a partner's) respond most to touch.

---

F

Foreplay

Intimate activity that builds arousal before penetrative sex or orgasm. The term "foreplay" somewhat undersells what it actually is — for many people, particularly those with vulvas, what's called foreplay is the primary event. Oral sex, manual stimulation, sensory touch, kissing, and intimate connection all fall within this space. There's no required sequence or checklist; foreplay is whatever the individuals involved want and enjoy.

---

G

G-spot

A sensitive area located on the anterior (front) wall of the vagina, approximately 2-3 inches in from the vaginal opening. The G-spot is thought to be part of the internal clitoral structure and tends to respond to firm, rhythmic pressure rather than light touch. Not everyone finds G-spot stimulation pleasurable, and that's entirely normal — anatomy and preference vary. Curved dildos and vibrators are often designed to reach this area. Browse [vibrators with curved heads](/collections/vibrators) to explore options.

Gua sha

An ancient East Asian wellness technique that uses a smooth-edged tool to apply gentle pressure to the skin, traditionally used on the face and body to improve circulation, reduce puffiness, and support lymphatic drainage. In the broader intimate wellness context, gua sha is part of the growing integration of self-care rituals — whole-body wellness practices that honor the connection between physical care and wellbeing.

---

H

Harness

A wearable device — typically made from leather, nylon, or rubber — designed to hold a dildo for strap-on use. Harnesses allow people of any anatomy to give penetrative pleasure. They vary in style (O-ring, jockstrap, thigh harness) and adjustability. A quality harness fits securely, stays in place, and uses an O-ring that accommodates your preferred dildo size.

Hypoallergenic

A material or product with a low likelihood of causing an allergic reaction. In the context of intimate products, hypoallergenic materials include medical-grade silicone, stainless steel, and borosilicate glass. Latex, certain rubber compounds, and fragrance additives are common sources of allergic response. If you have known sensitivities, always check material specifications before purchasing.

I

Intimate wellness

A broad term for the physical, emotional, and relational dimensions of sexual and intimate health. Intimate wellness includes understanding your own body, communicating honestly with partners, making informed product choices, and approaching sexuality as a legitimate part of overall health — not separate from it. DD Intimates exists within this space: products, education, and guidance that support the whole person.

ISO 3533:2021

The international standard published by the International Organization for Standardization specifically for sex toys and intimate products. It establishes requirements for chemical safety (phthalates, heavy metals), mechanical safety, electrical safety, and labeling. While voluntary in most countries, it represents the most rigorous third-party benchmark in the industry. Products designed and tested to ISO 3533:2021 standards have been held to an external measure that goes beyond brand claims. See our [Material Safety Guide](/blogs/news/material-safety-guide) for full details.

K

Kegel exercises

Voluntary contractions and relaxations of the pelvic floor muscles — the muscles that support the bladder, bowel, and uterus. Regular kegel exercises can improve urinary continence, support recovery after childbirth, and enhance sexual sensation by increasing blood flow and muscle tone in the pelvic region. Kegel exercises are recommended by pelvic floor physical therapists for a range of conditions and can be performed anywhere without equipment.

Kink

An umbrella term for sexual interests, practices, or fantasies that fall outside of conventional expectations — though what counts as "conventional" is largely cultural and shifts over time. Kink can include bondage, role play, power exchange, sensory play, and many other forms of consensual exploration. All ethical kink activity is grounded in the same principles as any other intimate encounter: consent, communication, and care.

---

L

Lubricant (water-based)

A water-soluble lubricant compatible with all intimate product materials, including silicone, glass, and latex condoms. Water-based lubricants are the most versatile option and the easiest to clean up. They dry out faster than other formulations and may need reapplication, but they are the safest choice for use with silicone toys (silicone-based lubricants can degrade silicone toy surfaces). Look for formulas that are glycerin-free if prone to yeast infections.

Lubricant (silicone-based)

A long-lasting lubricant that does not absorb into the skin or dry out as quickly as water-based formulas. Silicone lubricant is excellent for anal play, partnered sex, and any situation where reapplication is inconvenient. Important: silicone lubricant should never be used with silicone toys, as it can break down the toy's surface over time. Safe with glass, stainless steel, and ABS plastic products.

Lubricant (hybrid)

A formulation that blends water-based and silicone ingredients, aiming for the longevity of silicone lube with the compatibility of a water-based formula. Hybrid lubricants fall somewhere in between — longer lasting than pure water-based, with lower silicone content than pure silicone formulas. They are generally considered safe for silicone toys, but patch testing is advised for anyone uncertain.

---

M

Massage wand

A powerful vibrating device originally designed for muscle massage that became widely popular as a personal vibrator, most notably the Hitachi Magic Wand. Wand massagers typically offer stronger, broader vibration than other vibrator styles, making them particularly effective for external clitoral stimulation. Browse [DD Intimates wand options](/collections/vibrators) for body-safe choices.

Medical-grade silicone

The highest-quality formulation of silicone used in intimate products, characterized by non-porosity, chemical inertness, and the absence of fillers or blending agents. Medical-grade silicone is the same category of material used in surgical implants and long-term medical devices. It doesn't leach chemicals, won't harbor bacteria, and can withstand sterilization. It is widely considered the gold standard material for intimate products. See our full [Material Safety Guide](/blogs/news/material-safety-guide).

---

N

Nipple stimulation

Stimulation of the nipples — which are erogenous zones for many people of all genders — through touch, suction, vibration, temperature, or light pressure. Nipple sensitivity varies widely; some people find it intensely pleasurable, others find it neutral or uncomfortable. Nipple clamps, vibrators, and suction toys are products designed specifically for this type of stimulation.

Non-porous

A material property indicating that the surface contains no microscopic pores or channels in which bacteria, fungi, or residue can accumulate. Non-porous intimate products can be thoroughly cleaned and, depending on the material, sterilized between uses. Medical-grade silicone, borosilicate glass, and stainless steel are all non-porous. TPE and TPR are porous — an important distinction for hygiene and safety.

---

O

Orgasm gap

The documented disparity between orgasm rates across genders during heterosexual partnered sex. Research consistently shows that men in heterosexual relationships report achieving orgasm during sex at significantly higher rates than women — a gap attributed to differences in how sexual activity is typically structured, underemphasis on clitoral stimulation, and limited education about female sexual anatomy. Naming the orgasm gap is part of addressing it.

---

P

Pelvic floor

The group of muscles, ligaments, and connective tissue at the base of the pelvis that supports the bladder, bowel, and reproductive organs. Pelvic floor health affects urinary control, sexual function, and core stability. A pelvic floor that is too weak or too tight can contribute to pain, incontinence, or reduced sensation. Pelvic floor physical therapy is an underutilized but highly effective form of care.

Phthalate-free

A designation indicating that a product does not contain phthalates — a class of chemical plasticizers used to soften PVC and some rubber compounds. Phthalates are endocrine disruptors that can interfere with hormonal function, and their use in children's toys has been restricted by the FDA. In intimate products, where direct body contact is prolonged and absorption is high, phthalate-free labeling matters. All products sourced by DD Intimates are held to phthalate-free standards.

Prostate wellness

The prostate gland — located internally between the bladder and the base of the penis, accessible via the anterior wall of the rectum — is an erogenous zone for many people with male anatomy. Prostate stimulation can intensify orgasm and prostate massage has been explored in clinical literature as a supportive practice for certain prostate health concerns. Products designed for prostate stimulation are shaped with a curve to reach the gland and, for anal use, always include a flared base.

---

R

Rabbit vibrator

A dual-stimulation vibrator designed to provide internal G-spot stimulation via an insertable shaft while simultaneously stimulating the clitoris via a secondary arm (the "rabbit ears"). Rabbit vibrators are one of the most recognizable and popular vibrator styles and are designed specifically around the reality that most vulva-owners require clitoral stimulation to orgasm. Browse [DD Intimates vibrators](/collections/vibrators) for body-safe rabbit options.

Restraints

Physical items used to limit movement during consensual intimate play. Restraints range from soft ties and padded cuffs to more structured bondage implements. When using restraints, establish a safe word before beginning, check circulation regularly, and ensure the restrained partner can signal clearly if they need to stop. Always have a way to quickly release restraints — scissors nearby, quick-release buckles, or a simple knot.

---

S

Safe word

A pre-agreed word or signal used to pause or stop an intimate encounter, typically used in contexts involving role play, power exchange, or intensity that might make "no" ambiguous within the scene. Common systems include single words ("red" to stop, "yellow" to slow down) or non-verbal signals like dropping an object for situations where verbal communication is restricted. A safe word is not a sign that something is wrong — it's the infrastructure that makes trust possible.

Sensory play

Intimate or erotic activity that focuses on heightening or reducing sensory experience — sight, touch, temperature, sound, or smell. Sensory play can be as simple as a blindfold that redirects attention to touch, or as structured as incorporating ice, feathers, textured surfaces, or temperature-reactive toys. Sensory play is accessible to beginners and can be explored with or without partners.

Silicone

A synthetic polymer with a wide range of applications in medicine, electronics, and consumer products. In intimate products, "silicone" can describe anything from 100% medical-grade silicone to blended elastomers with only a fraction of silicone content. The word alone tells you less than you'd hope. Look for "100% silicone" or "medical-grade silicone" with no additional material qualifiers. See the [Material Safety Guide](/blogs/news/material-safety-guide) for verification methods.

Strap-on

A dildo-and-harness system that allows one partner to give penetrative stimulation. Strap-ons are used across all relationship configurations and are not specific to any gender or anatomy. The dildo is held in place by the harness and can be changed out for different sizes, shapes, and materials. Strap-on play benefits from generous lubrication and open communication about pace and pressure.

---

T

Temperature play

The use of heat or cold as a form of sensory stimulation during intimate play. Borosilicate glass and stainless steel products are particularly well-suited for temperature play — they can be warmed in a bowl of hot water or cooled briefly in the refrigerator, and they hold temperature safely during use. Always test the temperature on the inner wrist before use to avoid burns or discomfort. Browse [DD Intimates glass products](/collections/glass-dildos) for temperature play-compatible options.

Toy cleaner

A specially formulated liquid or spray designed to clean intimate products safely and effectively. Toy cleaners are pH-balanced and free from harsh chemicals that could degrade product materials or irritate sensitive tissue. They are particularly useful for porous materials (TPE, ABS) that cannot withstand boiling, and for motorized products that can't be fully submerged. Browse [DD Intimates toy cleaner options](/collections/toy-cleaner).

---

V

Vibrator

A battery or rechargeable powered device that produces oscillating vibration for sexual stimulation. Vibrators vary enormously in design, intensity, shape, and purpose — from small bullet vibrators for targeted stimulation to powerful wand massagers, insertable rabbit styles, and air-pulse devices that use pressure waves rather than direct contact. Browse the full [DD Intimates vibrators collection](/collections/vibrators).

Vulva

The external female genitalia, including the labia majora, labia minora, clitoral hood, clitoris, vaginal opening, and urethral opening. The vulva is often incorrectly referred to as the vagina — the vagina is the internal canal; the vulva is the external anatomy. Understanding the distinction is useful not just for communication, but for accurate sexual health education and product selection.

---

W

Wand massager

See: Massage wand. A large-headed, powerful vibrating device used for external stimulation. The term "wand" is often used interchangeably with "massage wand" and emphasizes both the shape and the intensity of vibration these devices provide.

Waterproof rating (IPX)

A standardized rating system — part of the International Protection Marking (IP Code) — that indicates how resistant an electronic product is to water ingress. In intimate products, the IPX rating tells you how safely the toy can be used with water and how thoroughly it can be cleaned.

Common ratings in intimate products:

A product marketed as "waterproof" without an IPX number is making an unverified claim. Look for the specific rating to understand exactly what the product can handle.
