It's all a matter of demand and supply. If you want to show your
underwear also nobody wants to see, therefore, you don't feel that
it's a big deal. But if a girl wants to show her underwear, many
guys will want to queue up and see. Therefore, they will either
want to charge money for you to see or they will only want to show
it to someone special, like their boyfriends or husbands.
