I found this book (https://researchsystem.canberra.edu.au/ws/portalfiles/portal/33689269/file) today. It is a dissertation by an Australian researcher with tons of case studies. I have read the first 20 pages or so and the case studies are really helpful for me as a man who was sexually abused as a child by my mother.
Awesome DG, it's spot on for you being a male who experienced SA by you mother. Males are often left out as I'm sure you know so this is quite relevant. I hope it helps.
I'm going to add it to the list of resources for CSA as we have some for males but not nearly enough.
