"NakedSword is set to dominate San Francisco's notorious Up Your Alley Fair with a weekend-long calendar of must-attend parties featuring porn superstars and beloved industry celebrities," a site rep said.
The Café is located at 2369 Market St. in the Castro, and Stud Bar can be found at 399 9th St. (at Harrison).
The NakedSword Up Your Alley booth on Sunday "will be swarming with porn stars, all on hand to chat with fans, sign headshots and give away the new Steve Cruz Condom," the rep said.
Performer-director Cruz produced the condom in conjunction with NakedSword and his safer-sex and sexual health awareness website HowIRoll.info.
The condom was designed by illustrator Glenn Hanson.
Cruz will press the flesh on Sunday alongside performers Tony Aziz, Bruno Bond, Samuel Colt, Allesio Romero and Scott Tanner.
Additionally, NakedSword CEO Tim Valenti will tape an episode of "The Tim & Roma Show" with co-host Sister Roma of the Sisters of Perpetual Indulgence.
Additional sponsored parties include Saturday night's Bay of Pigs dance event.
And on Sunday, "NakedSword will usher the sloppy weekend to a close with the prison-themed Play T-dance at DNA Lounge ," the rep said.
"With this exciting lineup of porn personalities and wild events, NakedSword continues to go beyond porn by playing party host to thousands of fun-loving gay men," Valenti said.
"Our company is proud to once again usher in a riveting weekend in addition to serving as the globe's leading membership gay porn portal."
