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

I am going threw the same thing, my boyfriend is in his "prime" but it seems i want more sex than he does!!. he isnt cheating on me i know that for a fact, we spend every minute together and he would never do that to me, i just dont know why this is happening. I always look my best for him i've even tried doing new things in bed, it seems to work ....but... for only that time. He tells me im beautiful and sexy all the time and he will rub my tummy and kiss my breasts but thats it. sometimes when i reach over to try to start something sexy he will push me away, THIS DOESNT happen all the time but it has happend so much that i dont even want to try anymore. He says he loves me and OMG he does! he goes out of his way to show it sometimes, and thats why i love him but i just dont know what to do i've tried everything and nothing is working i dont know if its me or if its him. I dont want to break up with him i love him and hes very nice but i dont want to ask for sex, HE should come to me BUT... if i wait for that the time will never come. This has never happend to me before normally i'm the one who has to push guys away when they wanna get a lill something, so i dont even know what to do!!! he says he wants to be respectable towards me and he says its not me i understand but a relationship with out sex is called friendship and he doesnt understand that. I like sex i want sex i dont want to give it up..but i think i might have to. Before i didnt even want to have sex with other guys but now i dont know if its because i love him and i can see us together that i want to have sex all the time with him, AND try new things that i have NEVER tried bfore or would ever try but with him its different i want every piece of him all the time. what can i do?? AM i just being a horn-ball or is this probem 4 real??

i have the same problem with my boyfriend and I'm only 18 years old. we have been together for almost 4 years now and we use to have sex as much as we could whenever an opportunity came up, now I have myself begging for sex. and I will constantly put on sexy lingerie and he will flat out reject me. Today I filled up the bathtubs and put in rose petals and light candles, and my boyfriend just decided he didn't want to come over and have sex even after I told him everything I just did. I will constantly whisper sexy things into his ear, surprised him w. oral sex, everything I read in cosmo to make a guy want you and nothing works for him. He tells me he still wants me that he just doesn't feel like having sex. We have sex probably once every one or two weeks, which is not enough for me and I try and talk to him about it but I can tell I just discourage him and push him away even more because he knows he isn't satisfying me. He's 18 years old, shouldn't he be full of hormones, I don't get it! and I'm pretty sure he's not cheating on me because I'm with him all the time, and I just would know. But I have no other ideas what this could be about, and I'm so sick of feeling miserable when he rejects me, I want some one to want me. But I do love him and I want to be with him. How do I fix this, and make myself happy again, it's making me beyond miserable and I'm beginning to resent him. HELP!

i think you just need to give him the space he needs, hes not cheating on you and there is nothing wrong with you.. Diane is right is everything she has said... Dont stress yourself over it, he probably has issues he is dealing with..

he is obviously not interested in you- duh!........

Sometimes men get tired of the same old thing. Its in their nature, yet most don't understand this. As relationships go from months to years, things may become to routine and taken for granted. Also consider if you have gained weight or any other appearance changes. Men are visual creatures and often require visual stimulation. I'm speaking from my experience. I put on a lot of weight and my man didn't look at me the same. I realized I had to keep up the efforts that I had when I landed him. We began to work out together out of the bed room and it led to working out in the bedroom.

Read Robert Jensen's "Getting off Pornography and the end of masculinity". It changed my life.
Here is a long list of other great books on the topic.

Porn is full of negativity and degradation. I would rather be single than have it in my life but I am very lucky to have a man who respects women completely and feels the same way as me...and we have a fantastic sex life.

EM, I am sorry but I strongly believe that you are in this pickle because you allow and even encourage porn. Porn is super degrading and brainwashes men in to seeing all women as objects. Of course it's easier to sit there and jerk off than to "work" a little to provide sexual intimacy. And he is clearly addicted...you can't just smoke a little bit if you are a smoker!
The whole threeway that he wants is because of porn.
You maybe need to start asking for what is best for you. Do you really want to come second to some pathetic porno fantasy? It is addictive as there is no back cover to the internet. Try reading soem literature about what porn REALLY does to men and how it affects them and braiwashes them. It emasulates men and makes women unhappy, insecure and used. Is that what you want? Try asking him to pit the porn aside for a week or two and see if he can or will do that for you. If he can't then he is addicted and if he can you both might like what happens.

I ve been dating my BF for 7 months. In the beggining sex was non stop. We have an amazing relationship but the sex is gone.
He is in front of his pc all day. When I come home from work, he spends 1 hour with me and again in front of the pc.
I dont' care if he watches porn. I encourage it we do it together. However he's become complaisant. We hardly go to bed together anymore. Although we are together everyday, I wish he could shut off the PC 2 nights a week just us time. If he is not on his pc he is on playstation. I cant do this anymore. I don't know what to say or do? He rather play with him self than have sex? Is this normal.? I'm at my sexual prime. We are both in our early 40's. I'm not demanding, I work, and I still have a high sex drive. This is not good. I don't want to loose him, I love him. However, I need him to understand how I feel. I think he is punishing me for not having a 3 way with another women? I am not into this anymore, I explained it to him from the beginning. I want this to work, what do I do. EM in NY
