Have I been sexually abused? *Possible trigger warning*

I think I may have been sexually abused as a child, and that I buried it deep into my sub conscious. 

I've always been creeped out by my biological father. As long as I can remember, I've felt uncomfortable, like he looks at me in a way a father shouldn't. My parents split up when I was young but I was always court ordered to spend my summers with him. I used to have a great relationship with my stepdad. He used to give me a hug and kiss every night before bed and one day (my mom says) I just stopped letting him say goodnight. I don't remember that, I don't remember most things from that part of my childhood. 

I moved in with my biological father when I was 17. Looking past my uneasy feelings of him, I wanted to try something new, and living in a different state with different people was a fresh start. 

It was great at first. Until he got comfortable. He's an alcoholic. Has at least a case a night. He doesn't go to bed until between 1-3am. He would crawl into my bed and lay with me for about an hour, stroking my forehead (me being 17/18 years old). I would just lay there frozen, trying to ignore the smell of beer on his breath. 

There have been some minor issues with my sex life in my marriage, I get very anxious when my husband rubs my forehead. I freak out if he hugs me and accidentally covers my ears. And sometimes when he touches my inner thighs (near private area) it hurts. Not like a surface skin pain, but like a deep uncomfortable muscle pain. 

If any of you have been through something like this, please speak up. I'm in the process of trying to find a counselor for these potential issues, but it's difficult if you have no memory of what happened.
