I love cartilage piercings and I would love to get another one. But I just can't pinpoint a time to get it. It takes nearly a year to heal and I constantly find myself doing things that would damage it, like wearing hats, helmets, getting my hair cut, or swimming.
My favorite piercings on guys are tongue piercings. I also like navel piercings for some odd reason. Completely unrealistic to expect from a guy, but I still love them.
I love my belly button ring a lot but I want to get my hips done, I probably won't because im so scared they will get caught on my pants a lot. On guys though I think it depends on the guy, sometimes lip but I've never actually had serious feeling for aguy who has had a piercing besides ear.
