I just looked at your past posts, and just from the first page, it seems obvious that you feel insecure about not having had as much sex as you think everyone else has had.
Well... The average number of girls that a guy sleeps with in a lifetime is 7. Don't feel bad, no matter what. If a guy died a virgin, he shouldn't feel bad. If a guy was at 200+, he shouldn't feel bad. It wasn't the right time for you. If it had been meant to happen, it would've. And when it is, it will. Over and over again. If you want it to happen, don't get bitter; just set up the conditions for it happening.
You're judging yourself--harshly--and it's not healthy. You aren't failing to get laid, because you aren't TRYING to get laid. There is no try. There is only do. You are just doing things. Sometimes you have sex. Sometimes you don't. Eventually you'll see that you had a lot more choice in the matter than you realized. You were CHOOSING not to have sex, strange as it may sound. You were subconsciously afraid that you'd get murdered by a boyfriend, or the girl would be psycho, or that you wouldn't enjoy it and then you wouldn't know what to do instead of chase girls, etc. You feel SAFE and SECURE as who you are now; you would be taking a RISK by becoming a ladies' man. (I don't know how universal that is, actually, but it was true for me. I thought I was insecure in myself, but actually I was afraid of the unknown; of the new people and circumstances I was inviting into my life.)
It's no big deal. It IS pretty ****ing easy to hook up with girls. You KNOW you aren't annoyed; you're JEALOUS/ENVIOUS. You realllllly want to be that guy.
FIND THAT GUY AND HANG OUT WITH HIM. It'll teach you a lot. Put your ego aside. Don't be embarrassed. YOU are the one who decides whether or not you're successful as a human. In my opinion, just being alive makes you successful. Girls are just fun. They have nothing to do with being a success, a failure, happy, or good.
