How can you tell if someone is gay?

Yeah is there a way to tell if a guy is gay? I know, stereotypes… and everyone doesn’t fit the stereotypes… There is a friend of mine which I have a huuge crush on. He knows about it, but there is something about him which makes me think he might be gay. He keeps saying he doesn’t like sex and songs that are all about sex. He has a lot of girl friends (as in female friends) and often gay guys will try and hit on him and ask him for his phone numbers. He tells me about those times and makes it sounds as if he doesn’t like it, but I’m not sure…

He will also hang out with girls just him and the girl, and do datey stuff like having dinner etc and still claiming they are just friends. And… he just keeps stressing the word “friends” and “friendship” a lot.

He has only had short relationships, and doesn’t seem like he wants to be tied down.

He is so difficult. He has had every opportunity to kiss me or make a move on me, because we are pretty close friends. But he keeps his distance.

Is he just not interested or do you think he could be gay?
(He knows I am interested in him)
