Genophobia (Losing ability to function with this)

First off, nobody has ever abused me in any way I can think of. I'm a virgin. Nobody has ever even kissed me, much less made a pass at me.

Now that this has been established, I feel that there is something very wrong with me. I identify as asexual, because I've never desired anyone ever. At all. That being said, I'm also positive I'm genophobic. When I see anything explicit on TV or online I break out into a cold swet and I have anxiety triggering asthma. I leave the room and cry in a corner because the anxiety is so bad.

I know this is not normal behavior. I mean, I should at the very least be able to be nonchalant about this. I'm an adult. WHen my friends talk about their sex lives, so long as it's not details, I can handle talking to them. However, it's wildly horrible for me have to think about this. It's like, not only am I incapable of being interested in someone, but I'm scared to death of being naked and vulnerable to someone else.

I can't have fantasies about anyone and me. I just get sick to my stomach. I can't imagine someone loving me because I know that they will evertually want to be intimate and i can't be. I just get so overwhelmingly lonely sometimes because my situation is so isolating that literally nobody can ever even be in a relationship with me.

Is there some kind of mental health thing or drugs I should be taking to fix what's going on in my head? I just at the very least would like to watch cable without dry heaving after someone gets lucky. It's very difficult to watch Game of Thrones and that is just sad.
