I feel that autogynephilia is a key thing but its hidden, perhaps because it's just difficult for people to grasp?
I found an accessible book edited by Dr Az Hakeem which was published last year. Dr Hakeem writes the introductory chapters which provide clear explanations for many aspects including chapter 4, 'Autogynaephilia The Men Who Want Vaginas'
The remainder of the book is made up of essays providing a range of perspectives by different writers.
TRANS: Exploring Gender Identity and Gender Dysphoria
"This book, the first of its kind, presents an easy-to-read, jargon-free guide to help anyone understand the terminology, the concept and the day-to-day reality of gender dysphoria and related concepts.
TRANS is a book for everyone - insightful enough for professionals, but accessible enough for all. Put simply, TRANS explains what gender dysphoria is, how it affects people, and what is available, medically and psychotherapeutically to support people with gender dysphoria."
