When we talk about cock rings, we refer to a circular toy that snugly fits around the base of the penis. Its job is to restrict blood flow around the area, thereby making your cock feel fuller and harder.
Strap-on dildos are meant to emulate the look and experience of a real penis. As the name indicates, the strap-on set-up consists of a dildo that sits in a harness worn around the waist or hips. The dildo features a flared base and the harness has an O-ring that holds it in position against the wearer’s pelvis.
