Strap-Ons
Strap-ons are harness systems worn around the hips that hold a dildo in place for penetrative sex. They allow any person to penetrate a partner vaginally or anally regardless of their own anatomy. The harness attaches to the body and secures the dildo via an O-ring or similar mount, keeping it stable during active thrusting.

Why Choose Strap-Ons
- Penetrative sex for any partner combination. A strap-on harness allows any person to penetrate a partner vaginally or anally regardless of their anatomy. This is used by people with vulvas who want to penetrate a partner, couples exploring pegging, same-sex couples who want penetrative sex, and trans and non-binary people whose bodies or gender identity make a harness the right tool for the sex they want to have.
- The receiving partner chooses the size and shape of penetration. Unlike sex where size is fixed by the penetrating partner's anatomy, strap-on sex allows the receiving partner to select exactly what they want in terms of dildo size, shape, curve, and material. This makes the experience highly adaptable to the receiving partner's preferences.
- The penetrating partner controls the pace and depth of penetration. Wearing a harness gives the penetrating partner full control over thrusting speed, depth, and angle in the same way a natural penis would. The harness distributes the movement across the hips and allows thrusting from the body rather than from the hands.
- A bullet vibrator in the harness stimulates the wearer during use. Many harnesses include a pocket at the front that holds a bullet vibrator against the wearer's clitoris or genitals during penetration. This provides stimulation for the penetrating partner simultaneously without either person holding a toy.
- Thigh harnesses offer alternative positioning and access. A thigh harness straps to the upper thigh rather than the hips and allows penetration from positions where a hip harness is impractical, including when the penetrating partner is seated or lying down. It also allows the penetrating partner to use their natural genitals simultaneously in some positions.
Types of Strap-Ons
Hip harnesses are the standard strap-on design. Straps go around the waist and through or around the thighs to hold the harness firmly against the front of the body during thrusting. Most use an O-ring mount for the dildo. They are available in nylon for easy washing or faux leather for a more structured fit. Browse the full strap-on dildos collection for compatible dildos to use with a harness.
Thigh harnesses strap to the upper thigh and hold the dildo against the side or front of the leg rather than the hips. The penetrating partner uses their thigh to penetrate while their own genitals remain accessible. These are useful in specific positions and as an addition to standard hip harness sex rather than a replacement.
Strapless strap-ons have a bulbous insertable end that is held inside the vagina by the wearer's own muscles, with a longer external shaft extending forward for penetrating a partner. No harness is required. The wearer receives internal stimulation from the inserted bulb while penetrating their partner. These require strong vaginal muscle control to hold the internal bulb in place during active use.
Harness and dildo sets bundle a compatible harness and dildo together in a matched package. The dildo base is confirmed to fit the harness O-ring and both items are sized to work together from the start. These are the simplest starting point for people new to strap-on sex. See the full For Couples collection for complete kits that include additional items alongside a harness and dildo.
Vibrating strap-on systems include a harness with a bullet vibrator pocket at the front so the wearer receives clitoral or genital stimulation during penetration, and in some designs the vibration also reaches the dildo and is felt by the receiving partner.

Who Buys Strap-Ons
Strap-ons are bought by any couple who wants penetrative sex to be possible or different from what their natural anatomy provides. This includes people with vulvas who want to penetrate a partner, couples exploring pegging where the receiving partner has a penis, same-sex couples who want vaginal or anal penetration, and trans and non-binary people for whom a harness is part of how they have sex.
Couples exploring role reversal buy strap-ons to shift which partner is in the penetrating role. The physical and psychological experience of switching roles is something some couples find adds significant novelty and intimacy to their sex life.
Receiving partners who want a specific size, shape, or material of penetration that does not match their partner's natural anatomy buy strap-on setups to access the physical experience they want. A strap-on dildo can be any size, any curve, and any material, giving the receiving partner a degree of control over their experience that natural sex cannot provide.
People who are curious about pegging, where a person with a vulva penetrates a person with a penis anally, buy strap-ons as the starting point for this specific activity. A slim silicone dildo in a well-fitted harness is the standard first pegging setup.
Choosing Strap-Ons
Harness fit is as important as dildo choice. A poorly fitting harness shifts position during thrusting, which disrupts control and comfort for both partners. Measure the waist and hips before purchasing and check the harness adjustability range. Most adjustable nylon harnesses fit a wide range of body sizes. Faux leather harnesses are less stretchy and require more precise sizing.
O-ring size determines dildo compatibility. Most harnesses use a standard O-ring that holds the dildo base in place during thrusting. Check the O-ring diameter of the harness against the base diameter of any dildo purchased separately. A base smaller than the O-ring will pass through during use. Many harnesses include multiple O-ring sizes to accommodate different dildos.
Dildo size is chosen by the receiving partner. The receiving partner's comfort and size preference determines which dildo is right. A dildo that is too large for the receiver is not useful regardless of other preferences. Discuss size preferences explicitly before buying. For a first pegging setup in particular, a slim silicone dildo of around 3 to 3.5 cm diameter is a sensible starting point.
Material for harness maintenance. Nylon harnesses can be machine washed, which makes them the most practical for regular use. Faux leather and genuine leather harnesses require spot cleaning and occasional conditioning. Genuine leather lasts longer and feels more structured but requires more maintenance and is more expensive.
Strapless requires muscle control. Strapless strap-ons are not suitable for everyone. They require the wearer to have sufficient vaginal muscle strength to hold the internal bulb in place during active thrusting. If vaginal muscle strength is uncertain, a hip harness is a more reliable starting point.
Looking After Your Strap-Ons
Wash nylon harnesses by hand or on a gentle machine cycle after use. Remove any metal hardware before washing where possible to prevent rust. Allow to air dry fully before storing. Wipe faux leather and genuine leather harnesses with a damp cloth and allow to dry away from heat. Condition genuine leather periodically to prevent cracking.
Clean silicone dildos used with the harness before and after every use with warm water and toy cleaner or mild soap. Non-motorised silicone dildos can be fully sterilised by boiling or dishwashing without detergent. Store the dildo and harness separately in clean pouches.
Inspect all straps, buckles, and O-rings before every session. A buckle that does not hold securely or a fraying strap should be replaced before use. A damaged O-ring should be replaced with a matching size before the next session.
Goes Well With
Water-based lubricant is essential for all dildo use with a strap-on harness. Apply generously to the dildo before penetration and reapply during extended sessions. For anal penetration, generous and repeated lubrication throughout the session is non-negotiable as the anus does not self-lubricate.
A bullet vibrator placed in the harness front pocket, where available, provides clitoral or genital stimulation for the penetrating partner during sex without either person holding a toy. Check harness descriptions for whether a bullet pocket is included before purchasing if this feature matters.
A prostate massager worn by the receiving partner during strap-on anal sex adds internal prostate stimulation alongside the anal penetration, producing a combined sensation that either toy alone cannot deliver.

Frequently asked questions
What is a strap-on and how does it work?
A strap-on is a harness worn around the hips that holds a dildo in place for penetrating a partner. The harness attaches around the waist and thighs using adjustable straps and buckles. The dildo is secured to the front of the harness via an O-ring that grips the flared base of the dildo. During sex, the wearer thrusts using their hips and the harness keeps the dildo stable and positioned correctly throughout. Strap-ons are used by any person who wants to penetrate a partner vaginally or anally regardless of their own anatomy.
How do I know which dildo is compatible with my harness?
Most strap-on harnesses use an O-ring system to hold the dildo. The base of the dildo must be wider than the O-ring diameter so it cannot pass through during use. Check the O-ring internal diameter of your harness and compare it to the base diameter of the dildo you want to use. Many harnesses include two or three O-ring sizes to accommodate a range of dildo bases. If buying a harness and dildo separately, confirm this compatibility before purchasing. If you buy a matched harness and dildo set, compatibility is already confirmed.
What size dildo should I use with a strap-on for the first time?
Choose a size based entirely on the receiving partner's comfort and experience with penetration. For a first strap-on session, a smooth silicone dildo with a diameter of around 3 to 3.5 cm and an insertable length of 12 to 14 cm is a practical starting point for most people new to strap-on penetration. For first-time pegging where the receiving partner has a penis, start at the lower end of that range and use generous anal lubricant. The receiving partner should communicate throughout the session and direct adjustments to depth and pace.
What is a strapless strap-on and who is it suitable for?
A strapless strap-on has a bulbous insertable end that is held inside the vagina by the wearer's own pelvic muscles, with a longer external shaft extending forward to penetrate a partner. No harness is required. The wearer receives internal stimulation from the inserted bulb while penetrating their partner. Strapless designs require the wearer to have sufficient vaginal muscle strength to hold the internal bulb in place during active thrusting. They are not suitable for everyone and people who are unsure of their muscle control will find a standard hip harness more reliable for a first strap-on session.
How do I fit and adjust a strap-on harness?
Put the harness on like underwear with the O-ring at the front centre. Tighten the waist strap so the harness sits firmly against the body without digging in uncomfortably. Adjust the leg or thigh straps so the harness does not shift during movement. The dildo should be positioned at a height and angle that allows comfortable thrusting from the hips. Test the stability by pushing against the dildo base before penetration to confirm it does not shift significantly under pressure. A well-fitted harness should feel stable during active thrusting without requiring manual adjustment mid-session.
