Why Doesn't my boyfriend want to have sex with me anymore?

I have this same problem, we were together a year, it was good, then it started going downhill, he ended up making out with his ex and breaking up with me. He later figured out she was just doing that to get back at him for breaking up with her. We got back together about 4 months later, and the sex was good again. It's been about 8 months since we got back together and now I'm lucky to get any once every month or two. When I mention it, he'll have sex with me, but it leaves me feeling like he's only doing it cause I complained and he wanted to shut me up. Whenever I try to talk to him about the issue, he just tells me that it's not me, that he loves me, and that he's just stressed out and tired. I understand him being stressed, his work is pretty stressful, and he's always tired cause he stays up playing video games all night. Sometimes I wonder if there's not somebody else and he's just afraid to say anything to me. The first time we were together, he lied to me a lot, I didn't know they were lies til we got back together and he admitted everything, so I know he's a decent liar. I wish he would talk to me, lately all he'll say, no matter what the question, is "I'm fine". I've started to feel I should just give up on the sex part of our relationship, but it's really making me feel depressed and undesirable. I'm at the point I don't know what to do. I love him and would like to be with him for a long time, I just wish he would open up to me about what the problem really is.

I'm going through the same thing but we've only been together 6 months and we live together. We used to have sex if not everyday surely twice a week. He has gained some weight and I know he doesn't like the way he looks anymore. He just got promoted at work and works overnight so he does get stressed out from work alot. I just feel really worried if he is cheating or has cheated we talk about sex and I know he loves me to death but I need that loving bond again, it's not like I need the sex but it makes me feel secure and loved. Any ideas on what I can do to get more answers from him or to get him to want to do it??

I don't want to point the finger at him or myself, but do I think it is healthy or normaly by any means to eaither person to be together but not have any sexual contact? nope. Who stays with someone for the " I love you ", but I'm not sexually attracted to you? I mean isn't that the whole reason you caught each others eye to begin with? because you thought he or she was cute? I have been with my boyfriend for almost five years and sex was never all that important to him. For me I am four years older and for me sex is. So I always felt like I was having to ask for it... So I started feeling bad about myself mentally and physically so I went from 5'8 130 to 110lbs. I worked out 7 days a week, and he still wasnt interested. So I knew it wasn't me... I personally think he has sex issues within himself. I just got tired of dealing with it so I do what I have to else where.

I'm in a similar situation. My boyfriend and I have been dating for a good 3 years now and he just recently seemed not interested in sex as much as he used to. We moved in together this last summer because we were attending school. Once we started getting busy with school and keeping on a part time job things just seemed to "die down" a bit in the bedroom. Nights and weekends when we would be home with each other sex hardly would come across either of our minds. Then the second I think of having sex or drop hints that I want (ahem) later he seems interested but then gets side tracked with homework/etc. But just recently he quit school because he realized that it was a career he didn't want to pursue. I respected him for that but he's been stressed about making me happy and his parents happy. Practically for the past week he's been crying and I think maybe the reason he's just not into sex right now is because he's too stressed out and that he wont find any satisfaction. We have great sex and he tells me and shows me everyday that he loves me. I just think that stress on your man may be a good factor to why there is no sex.

I have been with a guy for a little over two years now. I am 24 years old with a two year old daughter and he is 28. We started dating when i was pregnant with my daughter, so no its not his kid. But after i had my daughter we had all kinds of sex. But it started to decrease more and more. It has now been over a year since we last had sex or him even touching me. I keep thinking to myself it's because i have a kid right? i dont know. I has sat him down and talked with him about this sex fustration that i am having and he tells me all kinds of excuses. The excuses are different every time i ask him about it to. I have gotten " oh it's because we dont get along" , or i dont like the way you live( whatever that means) or " your not on birth control. I have gotten onto birth control a few times now because he told me that he would start having sex with me again if i had gotten myself on birth control. Once i do and it would be into 3 months of being on it, and i would bring it up to him again and he would get mad and say im preasuring him and he doesnt like it. So it would be months of being on birth control and he still wouldnt have sex with me, so then i give up and stop taking it. I dont know exactly what is going on with him. I love him very much and want to be with him, but the sex starvation that i been going through makes me want to look else where and forget about him. What should i do?

I am wondering if he has a problem down there.
Is he stressed out? Is he cheating on you with someone else?
I think for him to just stop drastically there has to be more going on than you think. If he's cheating he should just fess up already. We don't need to see you on Jerry or Maury anytime soon.
Does your bf feel less attractive around you? Some guys are really sensitive about talking about their feeling of what they look like, how they perform, and their self-esteem. If he's lacking in these departments it could deter him away from doing "the usual" or maybe he's bored of the "usual" and wants to try something different.

Why don't you do a little romancing on your end? Candle lite dinner, set the mood that he would be interested in, maybe he'll come back.
But I would try some communication first (How your day is, Is everything okay with family, something he's interested in. Maybe go to a concert)
Your whole relationship doesn't have to be based on sex. You can plan other fun things to do as well.
Maybe he just wants a break from it. (I know not the most exciting news you want to hear)
But do let us know how it goes :)

He's probably cheating on you

From a 70 yo husband and father:
First thought is he IS probably cheating.
Next, There is possibility that intervening motherhood makes a difference in your "desireability" even tho you're still beautiful.
Finally, when milk is free nobody will buy a cow. Casual sex got you into this relationship, so what's to sustain it?
NO, a healthy male does not just dry up. The glands continue to produce all thru life, and those glands are reaching out -- somewhere, and temptation is everywhere. If you're lucky, you may find the right combination of attractions to help "bring him home" What do YOU & HE think would makeup a Mother I'd Like to F...? That maybe where you need to be.
