How do I ask him to be my boyfriend?

Lol, this got me excited because there's a girl in my 6th period class that I really like and would be awesome if she asked me out. But lol that brings me to my point, that frankly I think most guys like getting asked out. It makes us feel good weather its someone we really don't like or somebody we really do like. So from my perspective I would do it in private somewhere make sure he's not around his friends it could make him nervous.
hope that helped!

I say just talk to him.. feel it out!! ask him to hang out casually, see where it goes.. if you already hang out a lot and you think he likes you then ask him!
but you should really hang out a lot first, get to know him, just do what feels right to you

Depends. Do you talk to this guy? Is he a friend of yours? If he's just some guy, then I wouldn't risk asking him out. On the other hand, if you know him, talk to him, etc. , and feel there is a connection between the both of you, then just plain out tell him. You can wait until there's no one around to ask him or invite him somewhere private. Hope that helps.
