I'm messed up.. I really need help. (writing this during a panic attack and I'm pregnant)

I hate sex. I've always hated it. It hurts at time and it doesn't feel good and i can't get into it. I can't get into anything sexual. And it caused a lot of issues with my husband and I. And I know it's my fault. And he knows how I feel so I'm not hiding it from him. He's an amazing man, really and truely the best guy in the world. I get butterflies just thinking about him. And it's not that I don't find him sexy. He's probably the most sexy man ever in the world. It's just me. And it makes me feel less of a woman, of a person in general. I'm so scared and upset and I don't know what to do..
