SF KuF = Kinksters under Forty

Kinky or kink-curious Bay Area men, ages 18 – 39.

2018 Summer KuF Parties are on top of us! (Or on bottom, as you prefer.) 

July 27: Up Your Alley Friday
September 28: Folsom Friday

(Want free admission? Volunteer for setup, cleanup, or a one-hour door shift. Message info@sfkuf.org if you’re interested.)

Both parties are at our new home, SF Catalyst, and follow the same schedule: open doors at 7pm (the early kinksters get the lockers), icebreakers until 7:45ish, optional orientation (strongly recommended for first-timers), and sexy times with an open dungeon at 8:00!

Doors close at 10pm. Assuming you’ve penetrated our entryway by then, the party goes through 1am. Check out our guidelines page to see what fun you can and can’t get up to to. In short, CONSENT is key–if you have it, tying, slapping, spitting, sucking, heavy fucking, whipping, spanking, edging, gangbangs, hair pulling, etc., are all good!! Without it, just don’t.

Visit our online marketplace to secure your admission. Email us at info@sfkuf.org if you have any questions!


New to KuF? Some highlights of what we’ve done:
– Our Folsom and Dore parties broke last year’s records, with 200+ hot, kinky guys making use of the slings, crosses, cages, and pretty much anything and anyone they could (consensually) put their hands on. Average age was about 26, with plenty under and over.

– We rented a cabin for a couple of kinky ski trips. We missed 2018 to scheduling, but this is an event we’re definitely repeating by popular demand. (Both times sold out almost immediately.) 12819231_824679864311002_2839822407301576215_o

– We’ve had multiple bondage workshops. Newbies learned basic ropework that can be used for sexy times. Intermediate levels learned harnesses and things that give you more to play with. A couple advanced rope enthusiasts learned two different suspension ties to take their subs off their feet.

– We’ve had fun!!! New kinky friends and play partners met. Kinky guys found kinky roommates, letting them (finally!) flog or electrotorture a hookup without waiting for the house to be empty. Boyfriends, Dom/sub, and “pack” relationships were formed and are going strong. Guys who are/were closeted about their kinks were able to come out to others about their healthy, amazing, and shared sexuality. Kinky guys could just be themselves without worrying about judgement. Yes!

BoltWhile the online KuF group has over 300 members, KuF itself is not about membership. We simply put on events for the 18 – 39 crowd, and invite them to attend. All types and levels of (in)experience should feel perfectly welcome! We do not split up play partners by age. Any ‘-uF’ (under Forty) attendee can sponsor up to two FaB (Forty and Better) guests. Sponsors and sponsees should arrive together. 

For social events, we’ve scaled Mount Diablo, had game and movie nights, caught a Broadway tour, and hit a bar or two. Lots of guys are introduced to Wicked Grounds, SF’s kinky coffee shop (we know, right?!), and chat over a tea or latte break. Have an idea for something else that might be fun? Let us know.

Workshops occur as members ask for them. Interested in flogging but never held a flogger? Were you a Boy Scout, but forgot all your knots? If you want to learn something, there’s a good chance someone in the group is capable and happy to teach it.
