He was probably just showing off, but u never know. He totally could have been making a move on u. If ur in that situation again maybe try complimenting him and maybe show urslef off some and see if he compliments u. And then maybe try to somehow throw in that ur gay or into guys or whatever u define ur sexual orientation as and see what he says. He could say that he is into guys too! Worst thing that happens is he could say that he isn't into guys, and atleast u would know then instead of wondering if he was coming on to u. Couldn't hurt to find out, who knows? He could be into guys and he could be into u and u two could have some fun hahaha
