Whats wrong with me?

I don't see myself as a prude or anything. But i don't know what's wrong with me. When it comes to sex, i don't like it. It feels really good, but everything inside me tells me its wrong, its gross and i feel extremely umcomfortable emotionally. I try to avoid sex because I'm afraid, i don't like feeling this way. I've been married for 8 years and i love my husband. This isn't something new, I've always been like this. I don't even know how to explain it. When I see sex scenes in movies, I feel extremely uncomfortable and like I want to leave the room. But I watch porn when I'm alone. I don't know it it has to do with my past at all. I've been molested multiple times as a child. Not raped but touched a lot by an uncle, and a few guys. These were on different times throughout my life. When i told my mother about my uncle, she didn't want me to tell anyone. And when my step dad found out about my cousin, he got very angry with me. So that's my background on that stuff, do you think it has to do with that?
