Though the SF Jacks , the gay jerk-off club now well into its third decade of existence in San Francisco, was started in the anxiety and agony of the AIDS epidemic, it shouldn't be readily categorized as a safe sex for swingers party. No, these are guys that just really like to get themselves off in the company of like-minded individuals. Unlike some of the cruiser bars and clubs around town, Jacks' weekly meetups take place in a well-lit room with minimal distractions from the show at hand – making it somewhat of a spiritual experience for some of its enthusiastic adherents. The peckerplay is moving operations to the Center for Sex and Culture  this week, so the time, we think, is ripe for a look back at the group's long line of love.
In? Just check out the group's regular newsletters dating from the early '80s to early '90s -- neatly preserved on its website  -- a fetching collage of Talmudic quotes, earnestly rendered dick art, and tantalizing record of theme nights past, including an appliance night, a Platonic love night (at which the Greek and the broad-shouldered were tempted with discounts on admission), and a flower-powered Hippiedick night. Now for the rest of the sex event explosion this week in the city.
Time to get classy, all you fluidly-gendered folk. This night, part of Femina Potens ' series of events at Mission Control, invites you to dress up dandy (top hat and spats), va-va-voom (backless gowns and vintage lingerie), or some mixture of the two (all of the above) and pose nattily while you are entertained by a talented evening cabaret.
Weds/28 8 p.m.-midnight, $10 for members of Mission Control, free for Femina Potens members

Calling all gay male artists – Mark I. Chester has a regular drawing session with quite a cast of characters assembled as models – so sharpen your pencils and get the sneer on that leather daddy just right or perfect your rendering of the shiny metal ring clamped about the life drawing model's balls... attached to a rope... attached to the ceiling. At any rate, do your part to render the art of fetish into whatever medium most fluffs your creativity.

“Come join us. We know what it's like to live on a faultline.” Such is the pitch from Shibari Relief, a kinky fundraiser set up to aide our buddies affected by the Japanese earthquake/tsunami/nuclear threat/kitchen sink. The group will be setting up shop with an auction of kinky art and two tickets to this year's Shibaricon  in Chicago, among other kinky goodies. Come down off your ropes, kinky community, and do something good for our neighbors across the Pacific.
