We get to know San Francisco’s leading gender mixers: Max Wolf Valerio, who reads from his book, Max, A Man; Jordy Jones and his net art; Texas Tomboy and his video art; Stafford, who explores new business venues and, together with Jordy Jones, organizes “Club Confidential,” the world’s leading gender bender event. We meet Hida, an intersexed woman, who happily inhabits the middle ground between male and female; and two extraordinary biological women who support transgender people: sex goddess Annie Sprinkle and ex-centerfold model Tornado, who was Stafford’s lover and is the self-proclaimed mother of Texas Tomboy. We take excursions into the life of the spotted hyena, a very special animal society. The female hyena has an enlarged clitoris that looks like a penis. Her bloodstream carries a large amount of testosterone especially when she’s pregnant. Our tour guide for the journey through shifting gender identities is Sandy Stone, also known as the “Goddess of Cyberspace,” who is Director of the ACTLab at the University of Texas at Austin.
