Most Helpful Guy
Why are you asking us? It sounds like you two are into one another, so just relax and go for it. You don't have to marry the guy. Just hang out with him more and enjoy his company.
If after a while you're not feeling much more beyond the initial rush of making out, then consider what you want to do then. But, until that happens, just let go and give it a shot.

Ask him out. See if you like him and go from there. The worst thing is to date someone only because you want a partner, not because you actually like them.
