In looking recently at an underwear/swimwear site for men, I couldn't help but notice a few of the male models having naval piercings. I sell body jewelry at a flea market but most the of the belly jewelry is worn by females. I have had a few guys who wore it. I'm undecided if I like it for men or not. I've also had a few guys who had their nipples pierced and didn't mind pulling up their shirt to show! What's your opinion?
