It sounds to me that you are suffering from extreme sexual frustration, and that no amount of counselling is going to help. You need to get laid, and fast.

If I were you, I would swallow my pride and find a pro. You should choose one in her mid to late thirties who is kind and compassionate. Be open with her and ask her to teach you about sex. You will reap great rewards, not only in self-confidence when you meet other women, but it will help you to shake off your neediness, which is unattractive.
The woman will enjoy teaching you (we all like to show off), and if you treat her like a person and not a sex-object, you will probably make a good friend who will teach you a lot more about women than you will ever learn on forums like this one.

I wish someone had given me this advice when I was younger.
