There's nothing wrong with you. Actually, it sounds like your upbringing was the culprit. You said yourself that you would avoid meeting guys because you wouldn't be able to explain to your parents that you were going out with a boy. That's a real problem. It sounds like you were brought up almost to be ashamed of wanting to date, have relationships and even sex. I doubt porn had anything to do with it and in truth was probably a secret way for you to explore sex without the fear of explaining it to your parents.

I would strongly suggest a therapist so you can work on relationships being okay for you.
