I wrote a transcript of this when it first aired:
[56:20]
SOM: Do you think AGP arrives, let's say, post-puberty, pre-puberty, have you got any kind of thoughts around this? Because, you know, there's a lot of conversation on that point.
MJB: Yup, so it is generally first evident when boys are in adolescence and they're getting a sex drive, and it's quite fascinating actually, because there's no way they learn this from other people, but they typically learn that they enjoy wearing their sister's or their mother's lingerie in private, looking at themselves in the mirror and masturbating. But for 90% of autogynephilic males, that's the first step.
However, Ken Zucker published a fascinating case report of a little boy, I think he's three or four, who's brought to the clinic because he is wearing his mother's panties and getting erections and masturbating. And he told me - wait, I think this is in the case report, I'm going to tell you anyway - that, in discussing this case, he learned that the father of this little boy was a secret cross-dresser.
SA: I've heard a lot of stories of father and son cross-dressing.
MJB: It is - there are only isolated case reports and anecdotes, but I believe that there is a strong genetic component in this and we can't - it's hard to see how we - you know, I can't be sure, but based on these case reports and stories I hear, I just believe that, that is true.
SA: Well, Mike Bailey, it was a really interesting conversation, we're so glad to have had you on.
MJB: I had a great time and - yeah, so I'll try to send you the link to the free version of my book and everybody should read it and have their parents and their children read it too.
[laughter]
SOM: Yeah, you're right!
SA: Read it to your five-year-olds before bed as a nice bedtime story.
MJB: Yes, and send Andrea James an email about how much they enjoyed it.
SA: Oh my gosh, I definitely will. [laughs] Thank you so much Mike, I hope you have a fantasic rest of your night.
MJB: Thank you, great to see you.
SOM: Thank you.
MJB: You too, you too.
