Yeah.

Women think Women are Pretty,
Men think Women are Pretty.

Neither of the two genders happens to think Men are Pretty. And very seldom do you find a "Pretty man".

Plus, when teenage boys grow up they beat the shit out of each other.
when teenage girls grow up they play games and have make out sections with each other to practice.

The two natures are different which makes them in complete agreement that two men should never be on each other.
