I don't mind if a guy wants to cover his blemishes a bit---- but eyeliner and mascara-- the whole shabang is a turn off. I'm not a fan of the emo/grunge look. lol, unless they're just joking around and let me doll them up for fun-- then it's hilariously acceptable :D
I feel I fit into the rockstars category =] I mean, 'professional musician' at least.
I haven't met another boy who wears makeup. I've maybe seen some guy in eyeliner at a gig but that's it, I'm the only one I've met. If more fellas are doing it though, I'll approve - I think its great. A good 'f*** you' to the whole enforced machismo lark, too.
