Kids Dress Up

As kids, boys and girls get to play dress up in completely different ways. Like boys get to be things like firefighters, cops, cowboys, doctors...and later in life, all these are seen as very sexy things to be. But girls, we get to dress up as housewives, and teachers, and maybe a patient. Never the doctor, always the patient. Why can't girls dress up like strippers, or hookers?? Or at least a sexy teacher.
