Strap-on dildo
A strap-on dildo (also strap-on, strapon or 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, with 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 vaginal sex, anal sex, oral sex, or solo or mutual masturbation. Sexual lubricant can be used to ease insertion, and strap-on dildos can be used by people of any gender or sexuality.
Harnesses
Harness types
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.
