New to group, looking for advice about sexual dysfunction

Hi all. Wow this site seems really great. I've been looking all over the internet for a support community. Unfortunatly there isn't a specific group for sexual problems, so this one seems the best bet. I've been with my boyfriend for a year now (we've actually known each other for over ten years, when we went out in high school.) He's the absolute love of my life and he loves me so much that he's putting up with extreme difficulties. I never want to have sex. Ever. I had some things happen in my past, but it hasn't affected me until now. This has been going on for well over 6 months. At first we had it all the time. He thinks it's him, that I don't want him. That's not it at all! And if I can make myself get going, it's great. It's not lack of sensation or pleasure. I just never want it. Has anyone else experienced this? I'm getting more and more depressed because I feel worthless and that I'm ruing his life. Please help!!!
