Helppppp

So there's this boy that i lost my virginity to when i was 15. We never dated, it was just a friends with benifits type thing. Then a few months later we did it again and i guess at that time he had a girlfriend but i didn't know and then shortly after that, they broke up. I'm currently 17 and we are still good friends, but he still mentions wanting to do it again. Do you think he could possibly have feelings? Or is he just asking for sex?
