I was at the online toy store and saw hundreds of different kinds of rings. Someone needs to explain these to me and I figured this was the best place to go. Do they really help? Do they give more pleasure to guy? Some of them look pretty strange, but then again some look really sexy. I'd love to see my H wearing?? one! Why do some have more than one ring? Is,it supposed to be something you would use at each session or is it just another tool in the bedroom? Thanks in advance.
