Ines Yes.. but she is a girl too.
Ever considered that your set of values (all girls equal, men different set of rules) does not automatically apply to the rest of the world? In many relationships who is dominant and who submits to that autority is not determined automatically by gender but based on the individual preferences of the 2 people involved - and it might well turn out that the dynamics are exactly reversed from what you know and prefer.
And with gay relationships there is obviously no automatism based on gender possible but it is always determined by what both sides like.
