Hole-y moley, it's time to say sayonara to Chaps , compadres – again. After assuming the name of the classic leather bar that called the DNA Lounge's address home in the '80s, Chaps II (as the 1225 Folsom location is formerly called) is switching identities to Kok Bar SF. Is the new moniker a sly wink to the once-was Kokpit bar of San Francisco gone by? Or have we perhaps been spending too much time at the new GLBT History Museum ? Regardless, Saturday the 19th will be Chaps last night open before it metamorphs into Kok, which will reopen April 1 at 9 p.m. for cruising good times.
Luck OH! the Irish
Alameda County Leather Corps event  on Sunday notwithstanding, I'm a bit disappointed in the dearth of St. Patty's themed sex events this year. C'mon, Mission Control, where was your call for leprechaun-themed codpieces and pots-of-gold augmented cleavage? Missed opportunites. Luckily, a brave band of gingers have taken up the call for Irish fun times -- check out Powerhouse's Patty's themed "party for the dirty gentleman," where you are cordially invited to kiss someone's Blarney stones.

The Blue Macaw

It's one thing to figger out that what your love life is missing is a trip to the polyamory buffet. But it's an entirely separate challenge to move confidently with that choice through the vanilla, monogamy-normalized world. This workshop with sex activist Julianne Carroll focuses on just that, blithely hopping about from the best ways to approach relationship agreements, confronting jealousy, emotional safety, to changing the world.
