I have several types. The metal one I have are the nicest but they are not Hypo allergenic and I get some skin rash after a few hours. I have two of them one being 3.75 Inches and the Other 4 Inches. The tightest one is the best. I wear them under my clothes. It makes for a nice bulge when I wear my thong underwear.
I have a few leather one, but I tend to neglect them.
I have a glan ring, which I love to wear. Haven't tried it for sex. But for masturbation it is awesome. Anyone else has experience with them ?
Anyone knows where I could get a nice metal cockring which would not cause a rash ?
