Something is wrong with me,,, FR

I'm a nervous wreck and plus I relate everything to cancer because the web is my worst enemy.( and I'm over dramatic .. Yes) So I started have sex in December of last year on a regular basis. But recently sex has been painful. Like this week. He's been gone for two and a half weeks. I hadn't done anything since he left. And when he came back it was like so tight and hurt when he put it in. And another thing .. I can't stay wet. I use to always get wet. But not anymore. I was wet before we even started having sex. And when we have sex for like 30 mins it starts to hurt. He will put my legs up by my head and it feels as though he's hitting something and it hurts like ... In my ovaries (lol) sorry. You know what I men's though.
