prostitution..
it's all about the money. period!
Or the woman gets in the prostitution for "easy" money,
Or they are forced to go into prostitution for someone else his/her money.
prostitution exist even at the beginning of civilisation.
if there weren't prostitutes , there would be much more rapes out there for sure.
Sex is an animal instinkt.
it is the one thing that can change a intelligent human into a reaving beast.
Sexual impulses can "override" your basic thoughts and doings... And when that happens , it's always dangerous for sexual harrasments...
And about the animals, you don't think raping occurs in the animal world?
Hormones, you love 'em or your hate them!
