Sorry to say, but the boy is being a jackass. Yes, sex should be enjoy by both partner but note that again, it should be enjoy by both. Not both must enjoy.

I feel sorry for the girl. Love is about passion. I don't see the passion in that boy who only thinks for him self, self-centred and simple minded guy. He's totally addicted to sex.

The other guys, please don't be like him. I do not say that sex is not important, but in this case, I vote no. Poor thing...
