I have been applying some of the stuff I've watched from RSD videos and recently went out Friday night and successfully danced with a good amount of girls, flirted/tease more than before and successfully got a girl to lick/bite her lip while talking to her. I attempted to sneakily go in for a kiss but she kept on covering her face (she was very shy and kissing in front of many people was not her thing I guess). I know I should have isolated her, but I was not thinking at the time.

I consider myself a great opener, but I cannot maintain an interesting conversation with a girl for more than 7 minutes, unless she has a great personality. This leads me to attempt to tease her and flirt with her to gauge her interest; it works sometimes, but for the most part, it doesn't because I run out of things to say and go to interview mode. The girl Friday night, I was teasing and talking to her for about 6 minutes and she was feeling it (smiling, biting lips) but then after that, she looked bored and like she wanted out. My friend was telling me to be more like myself, and I was. But the problem is that if I act like myself in the past, I tend to talk to girls like a regular "nice guy" in interview mode.

How can I prolong a conversation and keep her interested so that maybe I can bring her back to my dorm or hers so that we can have sex. I'm not afraid of being honest and saying, "wanna have sex" or "make love?" (to make it funnier I guess) but there is not enough attraction so girls will say no. I'm currently in college so I can't do game everyday, I don't want to be known as that guy on campus. So what can I do to improve teasing/flirting/communications with girls?

Thank you
