He has a point to some degree
As soon as a girl knows you're into her lots then she can do what she wants and think you'll put up with it
If she thinks you couldn't care too much if your with her or not than she'll work her ass off,sexually and not bein a complaning cow just so she can get interest from you
You have to show a nice side now and then,but we are animals and girls cant help wanting to be dominated by a man
