When I was out of town I had a chance to check out a club that was a hang-out for transsexuals. I met a few who did BDSM in addition to their regular services. Definitely interesting to interact with dommes of a different dimension. They don't need to strap it on -- they have the real thing! Speaking of t-girls, Joey Silvera has been putting out some high quality porns with them lately, even including genetic girls in some scenes. A funny and touching non-X-rated movie on the subject is Thailand's "Iron Ladies" which is based on the true story of a national championship volleyball team composed of crossdressers, transsexuals and gay men (over there they are all categorized together). It was the # 1 movie in that country and I highly recommend it.
