As an all-volunteer organization SigMa is entirely supported by membership dues, event cover fees, and donations!

Every donation is appreciated and helps us get closer to the amount needed to find a new space and re-open.

Many SigMa members do not walk through the doors on a regular basis. However, they continue to donate to support our purpose and efforts. Donations and membership helps those who come to SigMa for the first time. New folks can learn about BDSM, fetish, and kink, as well as meet other players who want a Safe, Sane, and Consensual (SSC) place to play.

There are two easy ways to donate – click the Donate button below to pay electronically via PayPal, Debit, or Credit card or send your donation to SigMa, PO Box 76335, Washington DC, 20013.

As a 501(c)(3) non-profit organization, donations to SigMa are tax deductible to the fullest extent of the law. If you are looking for a worthwhile tax deduction, SigMa is it.
