I can imagine masturbation not being as 'smooth' with the foreskin removed, but it is difficult to imagine that it would actually put people off the idea. If you have any photos of 'more unusual' piercings, thenI would be happy to include them as its always interesting so see what others do. I presume that during intercourse, the heavy ring clunking around inside the vagina must highten the sensation, but I really can't imagine it.
