I attend a small College. Last semester I was the only guy in my class and I had all the girls into me and they were so interested in my life and all I did.

Fast forward to now, there are 3 other guys in my class now, one came from abroad, he works out (like i used to) and cooks (which I also do). Just this evening all the girls in my class sat down and were asking him questions about his life and he was telling a story and I was observing all the girls in my class just sitting there captivated by what he was saying.

I sat behind them all just observing and it hit me. To be interesting you have to be mysterious and not give away too much info about yourself. For me being interesting isn't a problem but I've became very antisocial so it is now a major problem of mine.

I'm not jealous of him or anything if you're wondering he's a cool ass dude and me and him are friends. What I'm trying to show is the nature of females, once you're new around them and they don't know a lot about you they'll be interested and ask you a lot of questions, but as soon as they know more about you they'll move on to the next guy.

TLDR: Girls are only interested when they don't know much about you. Giving away too much information can kill attraction. Observe the behaviors of women around guys they are interested in getting to know and you'll be more successful.
