I'm 21 and I've been in a relationship with my boyfriend for two and a half years now. We go to the same university and have practically been living together in the same on-campus apartment for one and a half years. As our relationship has progressed, we've begun to have less and less sex. Neither of us initiates because we're always tired or stressed out. He says I should expect to not have much sex during the school year by now, but I don't understand how he is just constantly too stressed to even think about wanting to have sex. I've tried talking to him about it and he doesn't have much to say about it. A sexual life is important to me but the fact that he doesn't have much to say about it is worrying me regarding whether he doesn't find me attractive anymore or his testosterone levels are just canceled out by stress. If so, I don't know how to help him. Or help us.
