im not a big fan of guys+facial piercings, i dont find it attractive at all with the exception of Josh from Mariana's Trench
his lip ring is pretty hot.
an earring could be cool, and maybe nipple piercing. but that's it on a guy for me haha
as for tats, i dont like big tattoos on guys that cover your entire back or whatever, little things are fine (:
I've got 5 piercings in total, two on each ear lobe and my belly button. maybe one more on my cartilage and that'd be it for me. i have this big urge to get my tongue pierced but i dont wanna be stamped with the stereotype, that's mainly why i havent gotten it =/
