The story of my problems (and my life) - in a nutshell

[English isn't my first language, I apologize in advance for possible grammar mistakes.]

So here I am, finally writing my first post on this website. I've been visiting it for a long time just for the "Panic Button" feature, not giving much credit to the forum, but now I feel the need to tell you guys my story, for those who would like to read it and eventually help me out.

I'm L, and I'm 21. I've always been a good kid, everyone used to love me when I was at elementary school and I had lots of friends. Then middle school came and everything started to kinda fall apart. Of course that's the worst age possible (11-14), and I started having lots of personal problems for a series of reasons (this is not the place to talk about them). The results? Shyness, social anxiety and no self-confidence at all. Of course this is also the age when you get to know porn. For an insecure guy, that's very dangerous: I started not to hang out anymore, playing with my PC or Xbox everyday and waching porn/going to public webcam websites to do you know what.

That ended up destroying my social life completely. I spent my five years of high school hanging out with literally 2 friends and one of them even "betrayed" me eventually.

I'm now studying at the university and I've overcome every personal problem (with the help of a psychologist); besides I've now met really good friends I can rely on and I'm super happy about that.

But there's something that's tearing me apart: I'm still a virgin. I know that it's not that big of deal, I'm still young after all; but that leads to a strong sexual desire and how can you please it? Well, porn and masturbation are just around the corner.
My biggest problem is that I'm still quite shy, and I can't make the first move when it comes to girls. I feel terrible for wasting many time of my life just jerking off instead of taking action and because I wasted so many occasions to meet girls, so that's the reason why I decided to start writing here on the forum.
I bear a big burden deep inside of me because I'm ashamed as hell to tell people I'm still a virgin, and that keeps me from actually flirting with a girl due to my total lack of experience and fear of being rejected. I now want to start a new life, trying quitting masturbation and porn to give myself a boost in self-confidence, but still I bear that burden inside of me.

What do you guys think I should do? Anyone has/had the same problem?
