I like him but idk what to do...

I'm 16 in 11th grade and never had any relationships or did anything at all in my life.

So I'm kinda into this guy but I dont really know how to tell him I like him. We're friends, have the same class, and we always text each other but I dont want to ruin the friendship. I've always gotten rejected every time I confessed so now I'm too scared to confess, but I dont know what to do. I really want a boyfriend lol, can anyone help?
