The ultimate sex toy for couples of any gender: strap on harnesses can be used for gender bending, erectile dysfunction or just plain fun. A strap on harness is fastened around the hips or thighs to attach a dildo or flanged-base toy to your body. This allows you to penetrate your partner, hands-free. Most harnesses are adjustable and accommodate a variety of sizes and builds. Strap On Sex Kits include the harness, dildo and accessories come in one convenient package which is generally cheaper than buying these products separately. While strap on dildos are generally considered “lesbian only” sex toys, they are gaining popularity among straight couples who want to experiment with anal sex and role-playing. Strap on harnesses also allow men suffering from ED to penetrate their partners.
