CLUB: Hubba Hubba Revue and Bootie are mashing it up tonight, featuring five of the Bay Area's sexiest and sauciest burlesque performers, along with sets by DJ Tripp, guest DJ Billy Jam of New York City's WFMU, and SF's John!John! in the main room, and in the upstairs room, it's Apocalypso, featuring DJs Six, Candy, and Starr spinning the best indie electro. (9 p.m., DNA Lounge, 375 Eleventh Street)

EROTIC: The titillating The 2011 LIVE Masturbate-a-Thon: Arm(and Hand)-ageddon is happening tonight and tomorrow. The event is shorter and in a smaller venue this year, so women and couples are invited to take part in tonight's gathering. (Single men will have their own roped-off section at the event tomorrow.) Trans-identified folks are welcome either day. Proceeds benefit the Center for Sex & Culture. (7 to 10 p.m., Center for Sex & Culture, 1349 Mission)

ART: White Walls Gallery presents Indigo, a new collection of "meticulously layered, eye-jolting" paintings by San Francisco-based artist APEX, featuring an entire gallery full of graffiti-based pieces using stretched-denim instead of canvas. (7 to 11 p.m., White Walls, 835 Larkin Street)
