I have been with my boyfriend for 5 years, he just proposed in oct, we cuddle, kiss, have an amazing time together. We've lived together for the last year, our sex has progressively slowed down. I automatically assume he's cheating on me because he was always all about the sex and i find it hard to believe he just doesn't care for it anymore. I have asked him about it, and he says, its too much work, because after were done having sex he wants to go to sleep, and i dont get off from sex alone, he has to use foreplay after sex to get me off, so he says that he would rather just get off and go to sleep, and not have to worry about me enjoying it. This is affecting me dramatically, i was heavy when he met me and i am now about 60 pds heavier than when we first met, i feel disgusting and him not wanting ot have sex w. me makes me feel even worse. I dont want to hear that i should leave him, because obviously we are engaged to be married. Even when we talk about the wedding night, he'll say like oh were never gonna leave the room on the honeymoon, blah blah blah. So i mean i just don't get how a mans sex drive can go down so dramatically. i am lost and have no idea what else to do.
He used to be really fit also, he used to play basketball, workout, and all of that has also stopped. He has no motivation to do anything. I am worried about him. i think he has just completely gotten comfortable with this life of tv and video games and it's like i'm just fading into the background.
