Blogging from A to Z Challenge. For those unfamiliar with the concept, it's basically about 26 posts (we don't post Sundays), preferably on a theme, blogging our way through the alphabet from A to Z. My theme this year is all about TV Tropes, celebrating random tropes with some sort of weird, odd, unusual, controversial, or taboo element that appeals to my warped sense of literary adventure.
Continuing the theme, we have No Heterosexual Sex Allowed (check out the page for a complete definition, but your first guess is probably pretty close to the mark). After a quick perusal of the Literature examples provided, I've gotta go with:
"In A Brother's Price by Wen Spencer, heterosexual sex is allowed, but next to impossible for unmarried women, as men are so scarce. This leads to female prostitutes who try to appear as masculine as possible so attract female customers."
