Dating, first kiss

I'm 15 now and I haven't had a boyfriend at all and still haven't had my first kiss, I have a crush on this guy in my class me and him have become close now but I don't know what to do, because if I tell him I like him it might be weird but he could also like me back. I know it's only high school but I hate feeling that everyone else around me is dating someone then there's just me..... alone.

I really hope someone has some advice because it would be great to get advice from someone other than my friends.
