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

So it's not only me being abandoned? ((( We are 9 months now. It was perfect until the last month. Every time i want to initiate intimacy, he is tired, or busy, or needs to get up early. Im adventurous in bed, sexy lingerie and all... i thought maybe he has some problems, but no - today i found out he watches porn and masturbates on it. That lowers my confidence, i dont feel attractive and desired. I don't know what to do now.

Could it be that you have gain a bunch of weight? Its a real turnoff for guys when their girl was in good shape when they were dating, then they turn into a couch potato hamster as soon as things get serious.

Wow! I was worried that i was the only one suffering from this, because all the other couples seems so sweet together.
my bf and i have been dating for 8 month. for the first 6 month, we were quite active and he enjoyed dirty talking and jokes. but now, it seemed like that he is not that into physical anymore, and I am always the one who asks for "alone time" since he doesn't mention it anymore. we still hang out when ever we have time. but i just feel like i am unwanted, and he is not that sexually attracted to me anymore, which is making me very sad.

Wow, I can't believe so many women are dealing with this problem! It definitely makes me feel better. I've been seeing my boyfriend for 10 months, like many of you ladies, we had sex all the time for the first 4 or 5 months (from 1-2 times a day up to 4 or 5). In fact, he told me several times how satisfied he was, and that out of all his partners he felt that he was most sexually compatible with me. During that conversation he mentioned how he and his ex would rarely have sex and that he thinks sex is an integral part of a relationship (something we agree on). Now we have sex once a week maybe, he never initiates it and when I do it seems that he's just doing it because I want to. This is wrecking my confidence and making me wonder if this relationship is going anywhere at all.

I have the same problem.. only me and my partner's sex life has withered down to around three times a year. I really can't bare it anymore, especially when he jokes about needing condoms, and I'm like well we don't bloody use them. I have put on about 2 stone and I am really self conscious, but whenever I try and bring it up like when he mentions condoms, he gets all arsey and so I can't talk to him about it. I know this may sound naive, but I am seriously starting to think he may be gay. He's gone into acting and he's not the manliest of men. Or he's cheating. But it's a little reassuring that I'm not the only one.

I am so glad I am not alone. My boyfriend and I have been together almost 2 years. The first 6 months the sex was great and I never let it get any less on my end. I never said no to him and I always tried to do new exciting things. Every time I talk to him about being spontaneous he brushes it off. Like other posts I have read, he'll make a comment about wanting it later but then ignores any advances. Also like other posts..when I ask about it he obviously says nothing is wrong. He doesn't seem to care about my needs at all and for some reason he seems to prefer mastrubating over sex. He seems lazy and disinterested all the time. He comes up with so many excuses..but I know it's not the real reason "I'm tired" is the most common.. He smokes pot a lot too..which I think could be partof it.. but he always has smoked.. and in the beginning we had no issue... I'm just so confused. I don't want to be in a relationships where I don't have sex with someone I'm supposed to be in love with. It's driving me crazy...I had the opposite problem with my ex..What do I do? I've never felt so lost before... It's making me feel really bad about myself...and my relationship.. Help :(
