My sex life is going down the drain...

Vanessa
My boyfriend and I have been dating for three years now. We're both 21 so I know we're young and I guess still new to discovering more sexually. We've been living together for over a year now. We used to have sex ALL THE TIME. Whenever we had the chance we would. Like three times a day. I never really had someone I actually had real sex with besides the one I am with now. When I lost mine it was more just pressure and other times as well. Anyways... He's always horny and I'm not. I feel bad I don't give him any. But we always do the same thing. He goes down on me and it feels good but when he's on top it feels good at first but then gets boring. I don't like being on top I wear out quick. We live in my moms house in a room where everyone in the living room can hear so we keep it down. It's because of the kind of door we have. I don't know what kind of sex positions we should do or how to spice it up. I want to do something for him too instead of him doing all the work. Any advice? I'm not even interested in having sex but I think it's because I'm not enjoying it.
