Is there something wrong with me?? 😞

Does anyone else have this problem?

I want to have sex with my husband and we do. We have a good sex life. We’ve been together almost 6years and married for just over a year. BUT I’m so scared to make the first move for sex. Idk why. I can’t explain it. I think about it and play over these scenarios in my head and when I try to do it I freeze up and chicken out. So am I the only one?? How do I get over this “fear” if that’s what you want to call it.
