Lose virginity

So I’ve been talking to this really cute senior lately. He’s taken me out a couple times and he bought me ice cream and he says he wants to date me but we still aren’t technically together. I’m a 15 year old sophomore and i turn 16 in July and he turns 19 in June..

I think he wants to have sex and I have done other things like oral, fingering, yk but idk if I should go all the way. I want to but I’m scared he may be only using me
