I've recently realized that I have some deep seated negative thoughts about sex. I feel that it's dirty, wrong and I'm bad if I have sex or use sex toys. I've always had some pain when I've had sex but I thought it was because I was nervous that it would hurt, so I would clench and it would cause pain. But I just got my first vibrator and I couldn't use it because I was clenching so hard that it hurt to use it. I realized that it's not that I'm scared of the pain, it’s that deep down I have the belief that if you have sex, or use sex toys, that you're a bad person and that it's not normal. I know that this is untrue, but it’s impacting my sex life enormously. How do I overcome my irrational fears?
