B**M fraternity for gay men, hosting monthly play events in San Francisco. WE HOLD an annual Boot Camp run, plus social events and charitable fund raising.
WE ARE a social fraternity for men who engage in B**M -- the longest-standing gay B**M group in the western USA, with premier players who mentor by example. WE HAVE monthly play events at a private, well-equipped dungeon, supervised by safety monitors.

A Statement on Inclusion
The 15 Association, one of the world’s oldest men’s B**M organizations, has always been inclusive of trans men. Throughout the decades, we have sought to be more welcoming of all men in our community as the understanding of gender continues to evolve.
While preserving the affinity of male-centered spaces and masculine energy, The 15 commits to ensuring our events are welcoming of trans men and non-binary and intersex people who identify or present as masculine for the purposes of our events. The 15 additionally commits to educating our members to ensure they are informed and up to date on our inclusion policy.
The 15 unequivocally supports the freedom and rights of trans and gender-diverse people.
