Same as anyone else: "Hey, do you want to catch dinner and movie with me one night this weekend?" "Hey, do you want to go see a ball game/show/rodeo/play with me this weekend, I have tickets?" "Hey, do you want to grab a cup of coffee with me on Saturday afternoon and then go check out the farmer's market?" Etc.
Hey man, you wanna go get a bite to eat?
You can ask if a guy is gay or you can ask if a girl is gay. It doesn't matter. But you probably won't get the answer you want, unless the person you're asking about is openly gay.
Ask trust me just ask
You don't. Going after a straight guy will only end in disappointment. But if he's gay, then he's not a straight guy, so just ask him to go out with you.
you ask him
You ask him out first.
Ask him
They ask another gay guy that they like if they will go out with him! That question is as simple as heck
You can ask a guy if he is attracted to women as a polite way of finding out if he is gay or bisexual.
There's no better way to find out than ask the guy if he's gay. That way you will know and can move on if he is gay.
ummm ask him?
Just ask
Ask him. Only he can decide if he is or not.
