curious when it comes to belts I think that rules are supposed to be equal for both genders.
Can't see why. Girls can get pregnant, guys can't. 1/4 of the world dresses women to the teeth and covers their hair, guys go about as normal, in the west many fathers secretly (or not so secretly) feel pride when their teenage sons get something [sex that is], and anger when their daughters are the ones getting got [sex that is].
No matter how you slice it, it is the girls who need protection (if they are amenable to it).
