SF KuF = Kinksters under Forty

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

Coming Up: Folsom Friday Party!

We’re less than a week away from our biggest party of the year–“a multinational fuck-fest!” Our Up Your Alley (aka Dore) broke its third record in a row! Folsom is about to do the same. Come (again and again). Have fun with us!

Secure your entry by prepaying at our online store.

If you don’t know many people, or if you plan on coming solo, PLEASE come to the icebreaker before the party. It really makes it soooooo much easier to meet people. We wish it weren’t the case, but at a sex-positive venue, some guys find it harder to say hi to a stranger. What seems like a clique is often just a group that overcame their initial awkwardness because the icebreaker or orientation forced them to talk. At our last few parties, the guys who did the icebreaker walked away with FAR MORE connections than those who missed it. Seriously, come.


We are proud to announce that, thanks to our sponsors, attendees of both our UYA and Folsom parties get to walk away with passes for free admission to Blow Buddies in SF and Steamworks in Berkeley! Steamworks also provided a bunch of lube, as well as a few sexy jockstraps that you might be able to win, if you’re piggy enough!

2016 in Review 
– We had six play parties. 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 kinky ski trip and sold out almost immediately. We’re repeating the event by popular demand.12819231_824679864311002_2839822407301576215_o

– We 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 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 did our kinky cabin trip–a full weekend of skiing and snowboarding, slings and bondage, sex and snow, hot tubbing and sex, new friends and fun conversations, The Princess Bride, shared interests, and kinky sex! In warmer months, we’ve scaled Mount Diablo, saw the Broadway tour of Book of Mormon, hit a bar or two, and had a game night in the Polk. 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.
