So I'm 31 yrs old and my boyfriend is 25 yrs old.....We've been dateing for almost 4 yrs now and like all other relationships everything was great for the first 3 yrs and then our sex life started dropping .....we use to have sex at least once a week if not more but then for no reason at all he just stopped wanting it....He claimed at first he was tried from woring late like 12 or 1 am before he would get home but then he would stay up anyways and sit on facebook on nite dam near....He doesnt work there anymore and he hasnt for like 6 months now he went almost 2 months without working and we still never had sex so i know now that he was just saying that to get out of haveing sex....we went from haveing sex every week to maybe and idk yet cause we still havent had sex but i think its become a once every 2 month thing if that and if we do have sex i pretty much have to make him do it cause he wont anyother way...he says he still fines me very hot and all but hes not showing it.....Now he blames it on the kids that im to loud and they will here us if we try in the morening time but then he says at night hes to tried so i'm at my wits end idk what to think anymore thank god i have toys cause im in my sexually peek and he should be to....which leaves me to believe that hes getting it from someone else he does have a history of cheating on his pass g.f. but he swears that it was because he was only a kid then and he claims that he would never cheat on me but i still have my doubts just because of his pass.....just this pass week i found out he was watching porn on the computer which i really dont care bout that part the part that bugs me is how are you knowing this is a problem in our relationship and then your gonna watch porn and get yourself off rather then have sex with me......He says that his relationships always go that way lots of sex at first then it slows down to me thats not slowing down we our not having sex at all......Idk what to do anymore talking about it doesnt work he just gets mad at me and then says stupid stuff just because he knows it'll hurt me so i dont bring it up anymore and i dont even bother to try and get him in the mood anymore.....I know its not because I gained a bunch of weight from haveing 3 kids or let myself go i'm 5ft 9in and i weigh 115 lbs and im tone as hell so i know its not that ......if anyone else has gone through this or knows anything about why this is happening your suggestins would be greatly appreciated thanks.
