I think I have lost interest of having sex with my boyfriend. It's always the same positions (missionary, doggy, riding on top and bj), he don't want to try out new positions, he is always the first to cum and first to head to bed afterwards which leaves me unsatisfied with my sex life. Don't get me wrong, I'm sexually active and like trying new things (sexually). I've even tried to have a conversation with him about it but he says, "he's tired" (and lazy i assume) which led nowhere. I have to watch like porn to get pleasure... what should I do?
