Having sex...

So I'm 15 turning 16 in September and I've been talking to my boyfriend and I want to have sex and so does he but because he is 17 and I'm 15 and our relationship sort started not long ago month+ and have been talking for months (do love each other very much) we are going to start talking about it in a a month or two when we might want to do it but is it a good idea? We will be using protection. I know the cause and affects that could happen but he does have a car and nobody can really tell if anyone is a virgin or not sooo.

Should i?
