<human>: I have been with my BF for over 7 years. We met in high school and he was my first real BF, he went out with a couple of girls before this but never anything proper. 

We moved into a rented flat when I was 19 and then went on to buy a house together. For the past couple of years our relationship has been rocky. We argue a lot, don't really talk about how we feel and are hardly ever intimate.

I have repeatedly tried to initiate sex or some sort of intimacy but am rejected the majority of the time. I have spoke to him and asked him why this is but he refuses to give me a reason, he denies there is a problem. Aren't all 23 guys wanting sex?

I've tried everything to make this work, he just refuses to see that there are any problems except my frustration with him. I admit that sometimes I do get angry but with the constant rejection and consequent low self esteem, sometimes I can't help it.

I'm just worried that I am being too demanding and there is no problem like he says but I just feel so down! I feel as though sometimes I'm staying in this relationship because it is the easiest option and because I don't know anything else. He is the only guy I've ever been with or dated. Plus we have a house together and leaving him is a lot more difficult then it would be otherwise. Don't get me wrong I love him and have always seen myself growing old with him and having children etc. but the constant fighting and frustration is pushing me to breaking point.

Should I explore the outside world and see if there's a guy that can give me what I want? Or is this a "the grass is always greener on the other side" situation and I'm a really lucky girl that has found her man? Do all relationships go through this phase? What can I do to help him or should I get out now?

Can you provide a brief overview of the text?
