Ok so if your an attractive women at a bar or something, all you have to do is sit there and wait for a guy to come to you. If your a male, you have to be attractive (otherwise the girl won't take you seriously), interesting AND confident to get a girl. If your a women, you can be a bit shy and still get a date/hookup.
If your a shy male, your screwed. The girl will just become dis-interested and walk away, or if you say something wrong, your also screwed. I think women just have unreal expectations on how a guy should act and be. Women also have it easier in the looks department, because they can just cover up all their flaws with makeup, and enhance what they already have too.
