This week I'm speaking with Ray Blanchard, a psychologist, sexologist, who coined the term autogynephilia to describe those men that identify as women, often transitioning to live as women, who get a sexual excitement from imagining themselves as women.
And of course, this has got him into trouble from trans extremists.
When he praised a book The Man Who Would Be Queen by Michael Bailey he got into even more trouble.
Ray is fascinating because he also has a lot to say about whether or not being same-sex attracted is immutable, and also about various paraphilias or kinks as they are often referred to.
I visited Ray Blanchard at his home in Toronto, not that far away from Kenneth Zucker's home, who I had interviewed the week before.
