Minor hijack to show that even "women don't want to play prostitutes" is an untenable stereotype

. (I know that's not exactly what you're saying, but I wanted to give you an example of how that archetype can work in a game):
Back in the mid-nineties, I and my friends ran a couple large LARPs, one-shot evenings for which we'd create 60 or so fully-detailed characters with histories, connections to other PCs, goals, and funky powers.
Generally, we created characters to be gender-neutral. There was no reason that the ambulance driver who smuggled blood (no questions asked) from the hospital to the town mayor had to be female, no reason that the teenager who'd OD'd on huffing copier fluid and ended up in an insane asylum had to be male. The mayor, the chief of police, the linguistics professor, the bartender, could all be of either sex.
Some characters, however, were gender-specific. A homeless Vietnam Vet with PTSD and anger-management issues works much better as a male. A musician who practiced love 'em and leave 'em romance, and who had unknowingly parented a (now adult) child, works much better as a male.
And one of the characters I created was a courtesan, an Old-South-style belle from Atlanta who had built a tremendous political network by using her bed as an office. I thought it was a kickass character that would be a lot of fun to play: she'd be smart, powerful, vicious, sexy.
My co-GM was horrified when he saw the character, however, accused me of perpetuating the worst kinds of stereotypes, pressed hard to have the character removed from the mix entirely. We argued back and forth for awhile: he insisted that any woman who got the character would be horribly insulted.
Finally, I asked some of the women who would be playing in the game. Several of them said they'd love to play such a character. As a compromise, instead of handing that character out randomly, we gave it to one of the women who said they'd enjoy playing her.
While a hooker isn't exactly the easiest character type to pull off in D&D, an upper-class courtesan can work in a political game. Not at all a character to everyone's tastes, but some folks can get into such a role.
