HELP. Each time I get close to having an orgasm, my body just pulls away.

This happens at climax when I masturbate, during intercourse and while I am being eaten out.

The feeling right before orgasm is unbarable. Sometimes I actually feel nauseous. Also, very often I get spasms in my calves at climax and I have to stop because of the pain.

But feeling pain is not as common as simply not being able to handle how good it feels.

It just feels so good that I can't handle it. I feel like I'm going to faint, or vomit or break out in muscle spasms.

I want to orgasm. I am in a very healthy, loving relationship and I don't think I have any mental problems with sex. I think that having sex and orgasms is healthy and natural.

I've orgasmed probably twice in my life (once masturbating and once with my boyfriend), and it was incredible. I felt relaxed afterwards. But because I can't orgasm on a regular basis, I feel stressed afterwards and upset because I want to relieve my sexual tension.

Who else has experienced this and how can I make my body stop pulling away?

Should I ask my boyfriend to keep on going regardless of my telling him to stop? Should I ask him to hold me down and keep on going? I feel as though I need to be tied down so that I can't hide from the wonderful feeling of an orgasm.

Does anyone know what this is called, if this has a nick-name or is a condition? Does anyone know a website that describes tips on how to fix this? Does anyone have any tips from personal experience? I can't find anything on the web describing this problem or how to fix it!

HELP, please!
