Before we get to the week in Bay Area sex events, here is something you will want to be aware of: the ingenious ad campaign perpetuated by Baltimore activists from Force: Upsetting Rape Culture , who riffed off of questionable underwear design from Victoria's Secret. In doing so [as Baltimore Fishbowl reports ], the group ended up giving the company irrefutable proof that yes, their clientele cares about consent when in comes to sex.
"[VS'] 'Sure Thing' and 'Yes No Maybe' and 'NO peeking' underwear promote the idea of limitless availability," Force activists Hannah Brancato and Rebecca Nagle told Fishbowl. "Or on the other hand, leaving the choice up to the (presumably male) partner. The brand teaches girls to be coy instead of vocal and makes it seem uncool and unsexy to say no and mean it."
So what'd they do about it? They made a fake VS website promoting undies that say "No Means No" and "Ask First", and mounted a viral social media campaign, and soon enough the praise for VS' apparent conscious-dawning was rolling in via Twitter, Facebook, etc. from survivors of sexual assault and VS employees alike. The website and @LoveConsent Twitter handle were eventually shut down, but not before their effects were visible across the Interwebs.
So that was neat. On to the week in Bay sex.

It's not important what you have on underneath them, gentlemen -- panties, briefs, jocks, or otherwise. What matter is that you remove them, immediately. Your pants, of course.

International Day to End Violence Against Sex Workers
Ten years ago, feminist porn icons Annie Sprinkle and Robyn Few (RIP ) marked December 17th by holding a candlelight vigil for the 70-plus victims, many of them sex workers, of Washington State's Green River Killer. Since then, their simple ritual has spread across the globe , and the day has become an annual opportunity to call for justice for sex workers everywhere. Attend the vigil at the Center for Sex and Culture, where everyone is invited to add to a community altar to those who've passed, and the birth of a new PFLAG-style group for friends and family of sex workers will be announced.
