Is it normal that i am a goodlooking 26yr virgin?

Well my story is all kinds of messed up! This is my first time telling anyone on the planet actually. I am about to be 26yrs old and am terribly depressed about being lonely and unfulfilled sexually. I was an extremely self conscious and non-confident teen and that lasted through college pretty much (bad timing huh?). Well my female anxiety was so bad I would practically get panic attacks in any type of flirtatious situation. I avoided girls in that kind of environment the best I could (boy I regret that now!!). I kissed a girl at 17yr and since then have had some hooking up although still I held back. The worst part of my story is that I actually had chicks in the bedroom several times, at least 3 or 4 times. Each time I had thoughts racing through my head and I focused to much on trying to look like I knew what I was doing instead of being loose and enjoying myself. As a result I was unable to perform. This has killed whatever confidence I had. I do not think I can even have sex if I wanted to. I cannot maintain an erection at all with a girl and i really am not 100% sure why. I can barely get myself horny which is strange because I love internet porno!! I seem to only like porn or my imagination (masturbation)and can't do the real thing from so many years of avoiding it. I always gave the girl some excuse about being on drugs or medication that messed up my hard on but truth is i don't think this is the case. I had one GF when I was 19yr and it was a disaster. I forced myself to go out with her since I was embarrassed about being single. It was terrible I avoided physical relations with my own GF and she knew something was wrong. She ended up cheating on me cause i refused to have sex or do anything. Whats messed up was the point of going out with her was to get experience but I just couldn't do it. Now I am always working and never am even around girls anymore. I am sooooo lonely!! I feel empty and angry and jealous of all my friends who get laid non stop and talk about how great sex is. I don't even know what it feels like! And I can't do it if I had the chance! I don't want to give up because I have nothing else to live for. I have battled major depression and anxiety my whole life and have developed a terrible drug addiction the past couple years (Opiates like Oxy). I am clean now but on a ton of medication for substance abuse control, anxiety, depression, etc. I want to live a happy life with girls. I just don't think I am capable of Love which is another problem. I feel like girls aren't good enough for me which I know is wrong but can't help. I am a very Good looking, Smart, Athletic, Funny, and Nice guy. People always say how can I not have a girl? Any reactions here? Any advice or similar experiences? Any girls think they would bother giving me a chance? Maybe it's the medication? Or the anxiety?
