I found that many girls really don't know how guys are like. Because i have came across those questions frequently by women which you would laigh/smile and say " fuck! How innocent" I had pretty much idea on what woman are like... but still discovered and learned new interesting things which you would generally never come to know offline. Lol For example... The type of guy they generally like, how they expect from guys to approach them, how they expect from Guys to treat them in bed. I really learned here on why girls are never attracted to sweet kinda nice guys. Tbat question was running over my head for quite long time and it really explained on why am i still single.
That some of them lack empathy even more than I ever did. Other than that, GAG wasn't really my primary source of information.
I haven't learned much about girls other than there quick to tell you to dump someone. But I've learned a lot about guys especially how angry some guys can get about stuff that really isn't that serious.
