What do you think of this person?

A person's sexuality can not be determined by their actions, unless they have directly stated their sexuality.
Stereotyping homosexuals in the way you described could make him appear to be gay, but I wouldn't draw conclusions until he says something directy.
If you want to know for sure, try checking Facebook, Twitter, Tumblr, or anything else that he might put something on to tell people. Chances are, if he hasn't come right out and said anything, he could be afraid to come out and might not want people asking him. Some people are very proud of their sexuality. Others are secretive and offended if you ask.
So, I don't think its a yes or a no..because you can't truly draw a conclusion without such proof.
