Why are girls scared of me?

I know what you mean it happens. Women feel like they don't have to approach men because they usually have the sexist mindset that the man is supposed to chase the women. In their mind looking at you and smiling is putting themselves out there. If you don't do anything after that then it's like rejection for them. Women never get off their *** for men especially if they're hot and have guys hitting on them like every day.
