Ambisexuals are men who are erotically attracted to 'women with a penis'. Michael simply smiled and said, ""I've never been with a man. For me, a trans woman is a woman with masculine genitals, but she is still a woman. She looks like a woman and she acts like a woman."" It's the 21st century. Trans women sex workers go to great lengths to meet these needs. Tens of thousands of men like Michael currently live around the world. You might think this is a modern development made possible by sex-change technology. But meticulous research reveals that this unrecognised sexual orientation has persisted across all major cultures throughout recorded history. In spite of this, almost nothing is known about ambisexuality. What motivates their sexual orientation... and the trans women they are drawn to? This book has fascinating anecdotal stories and hard data which leads to deep insights. It will make you re-evaluate what you think you know about human sexuality in an era of growing acceptance of gender diversity and sexual expression.
