Sex at 15?

I'm in a very serious and committed relationship and I feel ready and comfortable with having sex. We've talked about it and we're going to be safe and use protection and make sure it's not while I'm ovulating (to the best of my ability). However, I am 15 and I've been reading a lot of the posts on this app and a lot of people are saying that's not okay or that they regret it. But I feel ready. I'm a virgin and so is he, but we've done everything else already. Should I do it?
