Well, all girls in that line of work that I've been (ahem)dating have been between 18 and 24. But methinks this is more of an issue of lifestyle/job choice as opposed to age. My last two girlfriends were super-responsible with money and they're both under 24. C'mon, it's such a fucking cliche: Girls are stripping/escorting/doing porn just until they graduate/get out of debt/get a down-payment for a house. It's alllllllllllllllllllll bullshit.
