Scared to orgasm

If you're a guy, that must be very uncomfortable afterwards. Or at least that's my experience.

If you're female, I think what you're doing probably isn't that unusual. Some women find it difficult to allow an orgasm to happen. They fear losing control of themselves, or all the sex-negative crap they've heard since they were small children makes them feel an overwhelming sense of guilt about the pleasure they're feeling. Or they think they don't deserve to feel so good for some deep-seated reason, and they shut themselves down.

It's easy for me to say, but I think you should just acknowledge your fear or guilt or whatever, and push on through. Orgasms are a completely normal experience, and they won't hurt you. In fact, they're good for you, while constantly leaving sexual tension unresolved is probably doing you nothing good at all for you.

I assume your male? If you have never orgasmed the feeling can be overwhelming and maybe a bit strange. Go for it. It's not going to kill you. Once you do you'll be wanking a lot! :)
