How to choose strap-ons
A strap-on setup is a harness plus a dildo, sold separately or as a kit. Harnesses come as adjustable strap harnesses, briefs-style harnesses and thigh harnesses; strapless strap-ons have an internal bulb instead.
Compare harness size range and adjustability, the O-ring size (it decides which dildos fit), and the dildo's insertable length, diameter and base: only dildos with a flared base work in a harness.
Strap-Ons FAQ
What is a strap-on?
A harness worn around the hips or thigh that holds a dildo, so the wearer can penetrate a partner hands-free. Strapless versions are held in place internally by the wearer.
Do all dildos fit in a harness?
No. The dildo needs a flared base wider than the harness O-ring, and its shaft must fit through the ring.
