A strap-on dildo (also strap-on, dildo harness) is a dildo designed to be worn, usually with a harness, during sexual activity. Harnesses and dildos are made in a wide variety of styles.
There are variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner.
A strap-on dildo can be used for a wide variety of sexual activities, including solo or mutual masturbation, as well as penetrative oral, anal, or vaginal sex. Sexual lubricant can be used to ease insertion.
Strap-on dildos can be used by people of any sexuality or gender, upon people of any sexuality or gender.
The first part of a strap-on setup is the harness, which connects the dildo to the wearer’s body, usually in a position similar to that of a male’s genitals. A good harness should be sturdy yet comfortable, and is often designed to provide stimulation for the wearer. Many types of harnesses are available, with different features and drawbacks. Some dildos do not need a harness or are built onto one; for these, please see the sections on dildo types and dildo attachment methods.
A 2-strap harness, in its most basic form, is similar to a g-string. One strap goes around the wearer’s waist, like a belt, while the other goes between the wearer’s legs and connects to the other strap in the middle at the lower back. While these are simple, many people find them uncomfortable because the strap rubs against the anus and other areas, and they sometimes do not hold the dildo very firmly, causing it to sag, flop, or twist.
Corsets and other clothing items
Strap-on harnesses built into various clothing items are available, most often as a corset or other item of lingerie. Some are designed to be worn underneath normal clothing for quick use (if done with the dildo in place, either to give the appearance of a penis or to be able to quickly initiate intercourse, this is sometimes called packing), while others take advantage of the additional strength and sturdiness an item of clothing can provide over a few straps, or just to integrate the strap-on into an erotic outfit.
Harnesses are not limited to the crotch, and indeed many types are available for other body parts. A popular one is a thigh harness, which attaches a dildo to the wearer’s thigh (or other part of the legs or arms, though this is much less common), allowing for many unique positions, as penetration is no longer limited to what could be done with a penis. Another unusual design attaches a dildo to the chin of the wearer, allowing vaginal penetration while performing anilingus or vice versa. Also, an additional design is a gag-style harness, in which a gag is inserted into the wearer’s mouth and a dildo protrudes at the other end.
Harnesses are available to attach dildos to just about any household object, allowing for many creative uses. A dildo could be attached to a chair, bed, or any other item of furniture, and penetrate someone during other activities, with or without a partner. Another item, while not technically a harness, but worth mentioning, is an inflatable ball, usually 9 to 18 inches (250 to 500 mm) diameter, made of sturdy rubber designed to support the weight of one or two people, with an attachment for a dildo on it. This allows many unique positions, such as double penetration for a woman by lying face down on the ball for vaginal penetration while her partner penetrates her anally doggy style, which is much more effective than a solid object due to the “bounce” of the ball. These inflatable balls are also quite popular for solo use.
