TRI ESS

TRI ESS (SSS, Sigma-Sigma-Sigma, Society for the Second Self) is a US-based social and support organization intended primarily for heterosexual crossdressers and their partners.

History

TRI ESS was founded by Virginia Prince in 1975 as a continuation of FPE, an existing distributed support group. In 1976, TRI ESS absorbed Mamselle, a smaller similar group. Also in 1976, Tri Ess rejected a proposal to merge/reconcile with the International Alliance, a similar group which had broken away from FPE/Tri Ess within recent years.

The group remains very active today with several chapters and independent members throughout the US.

Criticism

TRI ESS doctrine requires that members be heterosexual in orientation and not in pursuit of transition.
