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. A 2-strap harness is the most basic and 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. 3-strap harnesses have one strap around the wearer's waist, but instead of one strap between the legs, they have two straps, one around each thigh, rejoining the first strap near the front. This design leaves the genitals and rear uncovered, and attaches the dildo more firmly, giving the wearer more control.
