I'm 23M.

Few days ago i went with my friends and some of their friends that I met once. There was this girl that I started having some small talk with at the bar/party. While there was music we were having a few looks at each other and we were both smiling all the time as well as talking a little during songs. But that was our status during the whole night, just looking smiling and dancing a little.

There is something in me that I can't engage and move a step further. I have never approached a girl during a party, concert, bar, or tried making out with her on the spot or bring her home. I feel some kind of fear and embarrassment that when i do that something bad will happen or she will just push me away.

Often, after going to the club or a bar, I get very depressed when I come home and see all guys approaching girls and having success.

I don't know how to overcome this. I started feeling more attractive and I've been getting a lot of compliments from girls, but there is something blocking me that I can't materialize that. I never really had a 'game' and been single for years now. Usually on parties when I meet a person I kinda don't know what to do except stare and smile and small talk. I don't know how to continue as I've never done that. Almost all of my previous girls, they were the ones to first show the moves and escalate.

Help?
