Sex at 15?

I turned 15 last month, and recently I've been hooking up with a boy from school. He is very sweet, and understanding, like when I'm on my period he tells me it's natural and talks to me when I'm feeling shitty. I've given him 3 bjs, and he wants to eat me out soon. We are planning on having sex this summer and I'm really excited. I've talked to my doctor and I'm going to a teen clinic soon to talk about pregnancy prevention. We feel ready, and confident. Is this okay? Should I go through? Am I too young?
