I've had confidence issues all my life (17). Anyway, girls always like me but I don't really get too much. Up until about a month ago I was always pretty shy with meeting new girls but now I go out of my way to talk to them. I am very funny (not in a self-mocking type way), and I make them laugh and hang out with as many girls I can at parties. Last night I probably talked to about 20 girls all being somewhat charming etc. I am still not having success in getting them, but I also haven't made any moves. I feel like I am making progress and am getting better, and eventually will have game. any suggestions?

Edit: note that there is plenty of alcohol at these parties, but I've been having 3 or 4 drinks - getting tipsy and a bit smoother but not hammered.
