Okay, so this I can talk about Man Jewelry, or as My friend coined it, Man-ery, I think really varries on style. I wear alot of leather corded things, Stud bracelets, crosses and the like. The more thin something is the more delicate it looks. Most guys I know both cisgender and trans wear stuff on the thicker side, made of metal, leather, or bone (i.e. shark Teeth).
