What I'd his sexuality (repost)?

Ok so my best friend and I were talking and he thinks he's bi curious or metrosexual. I told him he's curious at the least cuz he'll say guys are cute or he'll say oh damn when there's a hot guy.but he's also had more sex with girls than fingers on my hands. But do metro people do that like me and him are so confused and like I told him if he really wanted to find out he could kiss me or something since I'm bi and I like him. Can some people help me out with this. P.S. I'm not a w*ore I don't offer help to anyone ever he's the only person I would make an exception for
