Straight men will often steal glances at attractive women from time to time; gay men will do the same at attractive men. Try to see if you can catch him stealing glances at men or women. Otherwise, there's not much you can do other than to ask--or ask him out.
when they ask a girl out
Some gay guys have a certain kind of lips from kissing intensely with other gay guys. No, because there appearance can make them look gay but they probably are not gay at all. No, you really can't. Unless the clothing DID have something on it that says that they like the opposite sex, there's no way you can tell at all.
if she's a gay girl, and by gay you mean homosexual, then changes are she doesn't like any guys.
If he prefers to date other guys.

You can't, really. Some guys who act "feminine" are straight; some guys who could rip your arm off are gay. But if you show you're comfortable with gay people by doing things like joining a gay-straight alliance, or objecting when people make "fag" jokes, gay guys will be more likely to trust you.
If they're gay, then sure, why not?
No. Only guys who are sexually attracted to other guys are gay.
Of course. Some guys are closer to other guys than they are with their girlfriends and are not gay.
Not all gay guys are good-looking. Not all good-looking guys are gay. Sorry!
Gay guys, straight guys, and bisexual guys can all get tattoos.
If he likes guys, he is gay or at least bisexual.
