Does he smile at you? Do you see him checking other guys' pecs, butts, or packages? Then he's gay, or the kind of straight man who will be flattered by being asked out.
---- There is no way to tell if someone is gay, and the only way to find out is to ask him (or his close friends)
you ask him
you ask him
If they want to kiss you
The only way to know is to ask her.

Are you a female? Just ask him if he likes you.
If he likes the girl who likes him, then yeah.

Another guy will express interest in you by talking to you, smiling at you, winking, perhaps stealing glances at you, etc. === ===
Just be yourself.
