Sexual Aversion Disorder

Wondering if you could give me some suggestions. I am a 19 year old male that not only has a lack of sexual interest but a fear of them. I can get close to girls (i.e. Hug etc…) and be fine but as soon as it takes either a flirtatious or sexual tenor I feel terrified and need to get out of the situation. I only ever get an erection or ejaculate during wet dreams (Wich has only happened a few times), which tend to be more like nightmares for me. I have no issues with sex nor do I find it disgusting or have any self-esteem issues. I can read about sexual intimacy it in romance novels etc.. but am unable to look at any form of pornography without feeling sick.

People are different. You do not have to engage in sex. There are many other ways to live a happy life.
