Hi im 31 years old and male, been with my fiance for about 4 years, we have two little girls and all live together. When we got together me and my woman had sex all the time like most couples do when its all fresh and new but as time moved on we dont have it hardly at all any more. I mean, I know it dies off a bit as time goes on but now its lucky if we even get intimate once per month!

She has a right go about it sometimes and says i'm trying to treat her like a slag. of course i'm not, i love her to bits, were not even married yet but the sex part has ended up like this already!

What can I do to make her see? she used to say shes parranoid in bed and wouldnt have the light on during sex and that past partners had made her not like sex etc, but its been 4 years now that were together plus sex started off o.k!

Sometimes we get close and I look forwrd to going to bed but when we get to bed she changes her mind and i cant help feeling let down and annoyed that its just another day of not being allowed to be with her. I'm a very loving person and like to hug and have sex etc but feel like I cant express myself in this way anymore and when I do actually get to have sex it doesnt feel as good anymore because it doesnt feel like she really wants me in this way now, and maybe its just that she feels sorry for me and thinks she better let me have her this time?
I'm gutted, like I said I love her more than anything, would never cheat on her, do anything for her, but in fact...she was the one who chose me in the beginning (fancied me and got the ball rolling) but now seems happier to drink some beer and go to sleep.

Please tell me what to do, I would never come on these forums to get advice but am at my limit now and dont know what to do!
