Too $hort: at times, in need of a partner who acts in adult films.

Too $hort luvs porn stars. In fact, sometimes he needs them. The Oakland rapper performed with a passel of them onstage at this year's AVN Awards, and if you need more proof, this: he's headlining next month's Cow Palace pervfest (handily stepping in to replace the now-defunct Exotic Erotic Ball), the XO Ball and Expo.

He joins a list that also includes adult flick luminaries Tori Black, Chanel Preston, Stoya, and the puzzle tattoo-covered, chainsaw-to-the-face wielding Enigma. What else will you find at the open-to-all-sexualities soirée on Folsom Street Fair weekend, besides another change to wear your Mr. S pyramid swirl pouch? Burlesque, a freak show, aerial performances, and erotic art and fashion. No indiscriminate groping please.
