Why does my girl friend want no sex?
	
	
		Me (18years) and my girlfriend (18years) have been dating for just over 3 years and known each other for 14 years. We both love each other very much I always treat her I take her to watch films, shopping, camping, meals, restaurants, and even home made meals with romance.
We did not rush into sex we first took it slow we started oral for about 2-3 months in the relation ship and then had sex in the 4th month, we both really loved it and we both said it was it was really great. This was going on for about four months, 2-3 a week. Then the oral and the sex just stopped just like that we did not have sex for 4 weeks, so I sat down with her and speak to her in a calm way. Later that day we had sex but this not sort the problem.
We then decided to get her on the pill because she did not want to be pregnant yet, at last I thought I found the problem but I was wrong about 1 month after the she had the pill she does not want it at all, but when I try to speak to her she does not even want to know and some time it can turn to a argument, I try to tell here how I fell but she takes it to offense and thinks I am being mardy over it all, but all I am doing is just talking to on how I feel but does not take the notice. So then I spiced things up so I brought her a vibrator but that did not even effect it we had sex about once every 2 months, I even try dressing up and sex games but that don't seem to work.
And now its just crumbled down, we have sex every 20 weeks now and we even miss sex on our birthdays, valentines day and even new years eve. I also found out she hates using condoms but she don't want to get pregnant, so either way we will not have it.
About our sex.
We had sex in in different positions and change all the time, we change oral sex and sex from time to time when she wants to and I can last a long time and I asked if there is anything she wants me to do and she's say no.  we even had sex blind folded and she said it was sooo intense and she wants to do it again but that day has not arrive, also when she is ON she wants it really bad but she don't want to have sex because of she feels its unhygienic  (which I fully respect that) so I don't win that way either 
Some one please help its destroying me and our relationship
