Me and my girlfriend started dating 6 years ago and had a great sex life. We even went through a period of having regular threesomes and foursomes, but gradually over time the sex got less and less frequent.

It got to the stage whereby she would get really annoyed by me if I mentioned sex or made sexual advances towards her.

We then split up for a year. She was in University and it was hard to see each other and the relationship fell apart.

Very soon after we split, she dated another guy and I know she had loads of sex with him. She even did anal, which she never wanted to do with me.

We then got back together about 18 months ago, and had a bit of sex, but now, again, she gets really angry if I even mention it. I really feel loved by her and she always taks about how I'm the one and we should get married etc and I feel the same about her regarding everything but our sex lives.

Whenever I see her naked, I make a point to say: "Wow" or make her feel wanted, but I get nothing. No teasing, no advances. Nothing.

When I go out drinking. I find myself chatting to other girls because it makes me feel wanted. I would never take it further, but it makes me feel good. I WANT THIS FROM MY GIRLFRIEND!

There are nights where I won't mention anything and try to be an overly perfect boyfriend in the hope that she'll do something, but it never comes and I get really angry inside!!

I know that because I don't get it, I talk about it too much, but I don't know what else to do. Is it me? Any help would be hugely appreciated :)
