I understand what you have said but i didn't mean anything about sex at this point. Im enjoying seeing this girl and we really do get along very well. In truth, she is not as mature as me but she is very mature for her age, acting as mature as most 15 year old girls i know. Both her parents and my parents know we are seeing each other and are fine with it, with the slight exception of her dad. She does have an older brother at my age but he's not really bothered, but then i do know him so i dont think he's going to say much.
I have mixed opinions so far, some mates are saying if i love her just carry on, dont go as far as sex but "sexual" acts are fine, other mates are saying not too but there is a slight bias because they dont know her, so any of them could just be saying this because they think shes a "slag" or maybe they are trying to protect me.
At the moment, im not going to break up with her, i dont play girls like that, i love her for who she is and i believe that if love is there, then you cant just leave it.

What do other people think about this age gap or any age gaps for that matter?
