Glory be OneTaste . This SF-based company is devoted to the singular pursuit of female pleasure, offering lessons in their “slow sex” technique, detailed re-programming of one's touch-stroke-lick that all but guarantees that at-times elusive female orgasm. Believe it. Fitness-business guru-crazy Tim Ferriss describes a class with OneTaste in his new book The 4-Hour Body as being highly informative and bewilderingly hands-on. He also likens the female genitalia to an Imperial Guard from Star Wars, but that is besides the point (kind of). At any rate, OneTaste is conducting a one-off course at the Polk Street Good Vibrations  this week on discovering your deepest desires (Mon/31), making it but one of the can't-miss sex events on offer out there in pervertlandia. Enjoy, kids!
Bare Chest Calendar semi-finals
For 28 years, iron-chested menfolk have bravely paraded their bulging pectorals about for a good cause – the Bare Chest Calendar, which raises money for the AIDS Emergency Fund and Positive Resources Center . You can nobly help in the effort, just attend the semi-final and final rounds of the contest that will determine next year's calendar boys and cheer your ass off. By the looks of the contenders, that shouldn't be too difficult.

Transgender HIV/STI testing
Sure, it happens every week, but that's no reason not to give St. James' Infirmary a shout-out over their excellent, sensitive testing and trans-hormone-knowledgeable services that are available each Thursday afternoon. With all the scary cuts in the area as of late (see event Sun/30), it's good to know that there are still safe, friendly places to go to stay healthy, happy, and sexy.
Thurs/27 1 – 4 p.m., free

Chaps is putting the call out for boot pigs, so oink oink Wilbur – grease up your city Stompers  and cruise to Folsom Street. There's nothing sexier for a leatherman than the threat of getting crushed under the stampede of hairy-chested hotties that will be thrusting out their steel toes for a buff by bootblack Miss V. The Stompers gang hosts and who's that behind the bar? The sexy David, that's who.
Sat/29 9 p.m. - 2 a.m., free

Hotties 4 H0m0 Health Care: A Fundraiser for Lyon-Martin Health Services
Not cool.  There's not enough clinics in this city-state-universe that cater to queer women and transgendered folk, and one of the finest, Lyon-Martin Health Services, is facing closure due to serious financial problems. How much do they need to keep their doors open? Try $250,000 – which sounds like a lot, but given all the hullabaloo the community is raising to keep the place afloat, it's totally doable. Here's one way to support the clinic: shaking your ass to DJ Bootie Klap and wriggling in time to performances by burlesque star Dottie Lux and friends. (Here's some other ways, too! )
Sun/30 7-10 p.m., $5-20 sliding scale

Hey ladies, Ms. Cat (leather community stalwart and 2010 Ms. Leather runner-up) is celebrating her birthday and she needs you to reel back that hand and give her a good day-of-birth spanking. The Citadel's female-only BDSM party, Eclipse, is back in action, which means you should pack up your toys, friends, or just come solo and open to this dungeon time-party time.
Sat/29 8 p.m. - 1 a.m., $25 members only

The Depths of Desire
Secret longings are all well and good, as long as the longers themselves know what they are. Local sex education group OneTaste (famed for the dissection of the female orgasm) breaks down what one can do to get at one's deepest longings and sassiest salaciousness.
Mon/31 6 – 8 p.m., $20-25
