Jumping down his throat but in a nice polite way

So my boyfriend and I have been dating for about three weeks now! It’s been going great he is a complete gentlemen... but I think that might be a problem!! I’ve liked this guy FOREVER (we’ve been friends for 5+ years) and now that our relationship finally evolved, I’m basically ready to jump down his throat. I don’t want to rush anything, but honestly just a little makeout sesh would be nice! Any thoughts/advice on how to progress our relationship sexually?
