Should I have sex?

So I have been talking to this guy for a little bit and honestly he is so fucking nice, he never asks for any pics or anything, never goes further then I want to, he and I can send ugly pics back and fourth and still find each other attractive, and he’s just really sweet and I find him really attractive. We haven’t really hung out though yet, but we have just talked about sex and how we want to lose it before we’re 18, so idk I honestly really like him, but also my friends think he’s weird cause he’s not as popular as them. But opinions on this?
