Strap-On Dildos
Strap-on dildos are insertable sex toys designed to be worn in a harness for penetrating a partner. They have a flared or O-ring compatible base that anchors the dildo securely in the harness during use, allowing the wearer to penetrate vaginally or anally regardless of their own anatomy. They are used by couples of all genders and orientations.

Why Choose Strap-On Dildos
- Allows penetration regardless of the wearer's anatomy. A strap-on dildo worn in a harness gives anyone the ability to penetrate a partner vaginally or anally. This is used by people with vulvas who want to penetrate a partner, by couples where one partner wants to peg the other, and in any pairing where harness-based penetration is part of the sexual dynamic.
- The dildo is chosen for the receiving partner's comfort and preference. Unlike sex with a partner where size is fixed, strap-on sex allows the receiving partner to choose the exact size, shape, and material of what penetrates them. This makes strap-on sex highly customisable and allows the receiving partner to communicate and adjust their experience in a way that is not always possible otherwise.
- Non-porous silicone can be shared safely with a condom or full sterilisation. Body-safe silicone strap-on dildos can be used between partners with a condom for each use or sterilised between sessions. This makes them hygienic for shared use across partners in a way that porous materials cannot be.
- Available in shapes and sizes not found in a natural penis. Strap-on dildos come in smooth non-realistic designs, curved G-spot and prostate-targeting shapes, extra-large sizes, fantasy shapes, and textured surfaces that no natural penis replicates. This gives receiving partners access to physical experiences beyond what partnered sex with a natural penis can provide.
- Vibrating options stimulate both the wearer and the receiver. Some strap-on dildos include a vibrating component or are compatible with a bullet vibrator inserted into the base, transmitting vibration to the wearer through the harness while the dildo stimulates the receiving partner during penetration.
Types of Strap-On Dildos
Non-realistic smooth silicone strap-on dildos have a uniform, abstract shaft without anatomical detail. These are the most versatile strap-on dildo type because their smooth surface is easy to clean, comfortable for both vaginal and anal use, and available in a wide range of sizes. Most have a flared base compatible with standard O-ring harnesses. Browse the full strap-ons collection for complete harness and dildo sets.
Realistic strap-on dildos are shaped with a defined glans, surface veining, and realistic skin tones. They provide the visual and physical experience of realistic penetration for the receiving partner. The surface texture creates additional friction during use compared to a smooth design.
Curved strap-on dildos have an upward curve designed to target the G-spot during vaginal use or the prostate during anal use. When worn in a harness, the curve needs to be oriented correctly for the intended use. These are chosen specifically by couples where the receiving partner wants targeted internal stimulation rather than general penetration.
Double-ended strap-on dildos have insertable ends at both extremities. The shorter end is inserted vaginally into the wearer and held in place by the vaginal muscles, while the longer end penetrates the partner. The strapless design provides internal stimulation for the wearer during use without a harness. See the full realistic dildos collection for shaped options suitable for harness mounting.
Vibrating strap-on dildos include a bullet vibrator pocket or built-in motor that vibrates during use. The vibration is felt by the receiving partner during penetration and some designs also transmit vibration back through the harness to stimulate the wearer.
Extra-large strap-on dildos are proportioned beyond standard sizes for receiving partners who specifically want a fuller or larger penetrative experience than average-sized designs provide. These require prior experience with penetrative toys and warm-up before use.

Who Buys Strap-On Dildos
Strap-on dildos are bought by couples where one partner wants to penetrate the other using a harness. This includes people with vulvas who want to penetrate a partner vaginally or anally, couples who want to try pegging where the receiving partner has a penis, same-sex couples where penetration is part of their sex life, and any pairing where harness-based penetration is desired regardless of the anatomy involved.
People who want to give their partner the specific penetrative experience of a particular size, shape, or curve that does not match their natural anatomy buy strap-on dildos specifically for what the receiving partner wants rather than what the wearer can provide naturally.
Trans and non-binary people use strap-on dildos as packers, gender-affirming tools, and penetrative implements that align with their identity and the type of sex they want to have. Purpose-built strap-on dildos are more secure and comfortable for this use than improvised solutions.
Couples who want to explore role reversal or power-exchange dynamics buy strap-on dildos as the physical tool for the penetrating role to shift between partners.
Choosing Strap-On Dildos
Size is chosen for the receiving partner, not the wearer. The receiving partner's comfort, size preference, and experience level determines which dildo is right. A dildo that is too large for the receiver is uncomfortable regardless of what the wearer prefers. Start with a size the receiving partner knows they are comfortable with and work from there.
Confirm O-ring compatibility with your harness before buying. Most strap-on harnesses use an O-ring system that holds the base of the dildo. The base of the dildo must be wider than the O-ring diameter to stay in place during use. Check the base diameter of the dildo against the O-ring size of your harness. Many harnesses include multiple O-ring sizes for flexibility. If buying a dildo and harness separately, confirm compatibility before purchasing both.
Material for hygiene and feel. Body-safe silicone is the standard for strap-on dildos used on a partner. It is non-porous, easy to fully sterilise between sessions, and safe for both vaginal and anal use. TPE is softer and feels more realistic but is porous and cannot be fully sanitised between uses without a condom. For shared use between partners, silicone is the hygienically correct choice.
Realistic versus smooth for the receiver. A smooth dildo produces less friction and is more comfortable for longer sessions or for people new to strap-on sex. A realistic dildo with surface veining produces more texture during penetration. Ask the receiving partner which they prefer rather than choosing based on aesthetics alone.
Curve direction for targeted stimulation. If using a curved strap-on dildo for G-spot or prostate stimulation, confirm the direction of the curve produces the right angle when worn in the harness. Some harnesses angle the dildo slightly downward, which may work against an upward curve. Check reviews from couples who specifically used the dildo for targeted stimulation in a harness context.
Looking After Your Strap-On Dildos
Clean strap-on dildos before and after every use. Silicone dildos without motors can be boiled for 3 minutes or run through a dishwasher without detergent for full sterilisation between partners. At minimum, wash with warm water and toy cleaner or mild soap and rinse thoroughly after every use.
Use water-based lubricant with silicone strap-on dildos. Apply generously to the dildo before penetration and reapply during use as needed. For anal use specifically, apply lubricant to both the dildo and the receiving partner's anal opening and reapply throughout the session.
Store the dildo separately from the harness in a clean pouch. Check harness straps, buckles, and O-ring integrity before each use. A harness with worn or fraying straps should be replaced before use continues.
Goes Well With
A strap-on harness is the essential companion for a strap-on dildo. The harness holds the dildo securely in place during penetration and the fit of the harness determines how stable and controlled the thrusting motion feels. A well-fitting harness makes strap-on sex significantly more comfortable and effective for both partners than a poorly fitted one. Harnesses are available in the strap-ons section of the For Couples collection.
Water-based lubricant applied generously to the dildo before use and reapplied during extended sessions keeps penetration comfortable for the receiving partner. For anal use in particular, generous and repeated lubrication is non-negotiable.
A bullet vibrator inserted into the base pocket of harness-compatible dildos that have this feature transmits vibration through the harness to the wearer during penetration, providing stimulation for both partners simultaneously without additional toys.

Frequently asked questions
What is a strap-on dildo and how is it different from a regular dildo?
A strap-on dildo is specifically designed to be worn in a harness for penetrating a partner. The key difference from a regular dildo is the base. A strap-on dildo has a flared base sized to be held securely in a harness O-ring during active thrusting without slipping through. A regular dildo may have a flared base for safety but is not necessarily sized or shaped for harness mounting. Strap-on dildos are typically made from body-safe silicone for hygienic shared use and are available in smooth, realistic, and curved designs depending on what the receiving partner prefers.
How do I choose the right size strap-on dildo?
Size should be chosen based entirely on the receiving partner's comfort and preference, not the wearer's. Ask the receiving partner what insertable length and shaft diameter they are comfortable with based on prior experience. If the receiving partner is new to penetrative sex or strap-on sex, start with a smaller diameter, around 3 to 3.5 cm, and a moderate insertable length of 12 to 14 cm. A dildo that is too large for the receiver is uncomfortable regardless of what either partner expects. You can always try larger sizes in future sessions once you know the initial size is comfortable.
How do I check if a strap-on dildo is compatible with my harness?
Most strap-on harnesses use an O-ring system. The base of the dildo must be wider than the diameter of the O-ring to stay in place during use. Check the O-ring diameter of your harness and compare it to the base diameter of the dildo. Many harnesses include multiple O-ring sizes to fit different dildo bases. If buying both a harness and dildo separately, look for this information in the product descriptions of both items. Some harnesses and dildos are sold as matched sets, which removes the compatibility question entirely.
Can strap-on dildos be used for both vaginal and anal penetration?
Yes. Most body-safe silicone strap-on dildos are suitable for both vaginal and anal use. For anal use specifically, a flared base is essential to prevent full insertion, and silicone's non-porous surface allows full sterilisation between uses. Do not use the same dildo anally and then vaginally in the same session without sterilising or changing a condom between uses, as anal bacteria can cause vaginal infections. For anal use, use generous water-based lubricant applied to both the dildo and the receiving partner's anal opening, and reapply throughout the session.
Does the wearer feel anything during strap-on sex?
In standard harness-based strap-on sex, the wearer does not feel direct penetrative sensation because the dildo is held externally by the harness. However, the wearer may feel indirect stimulation through the harness pressing against their body during thrusting. Some harnesses have a pocket for a bullet vibrator that sits against the wearer's genitals during use. Double-ended strapless strap-on dildos have an insertable end for the wearer held by vaginal muscles, providing direct internal stimulation during penetration. Vibrating strap-on dildos transmit vibration through the harness base to the wearer depending on the design.
