Im 23, been with my bf for 3 years. Been having sex for less than 2 years. When we first started having sex, it was good....great. No problems. But in the pass 6 months or so our sex life just went downhill. We havent had "decent" sex. We went from maybe 3-4 times a week to if any 2 times a month!! Even then, its probably for about 5-10 minutes. Either we are not in the mood, its hot, w/e the excuse is. He brought it up recently how we havent had good sex in maybe 2 months. Then he said "I" dont seem to be into the sex as much as before. Honestly, and I dont know how to tell him this but its not that I dont enjoy the sex, I do. I get uncomfortable when he's on top of me bc he's sort of gained a lot of weight. He used to be 160 or so, well build. Now hes a bit below 200. Im very petite & when hes on top I'm too busy focusing on the "gut" than on the sex. It hurts when hes on top like if I cant breath. Me being on top doesnt really change much...I dont know what to do.
Help?
