Erections happen when arteries leading into the penis dilate, making the penis bigger than usual, while veins leading away from the penis constrict, trapping as much blood as possible in there. It can also help make erections feel harder. Well, this restriction can feel highly pleasurable for some people. Learning this might inspire a very valid question: Why the hell would someone want that?!?! A cock ring is exactly what it sounds like: A ring-shaped sex toy that goes around a penis or dildo to squeeze the shaft or shaft and balls.
Whatever you call these devices, they’re the unsung heroes of many a sexual escapade.
