Recently the desire to have your genitalia cut off in order to pass as a member of the opposite sex was considered a form of body dysphoria. Can you point at the scientific breakthrough that changed that? I've been under the assumption it was a social change.

In some cultures, eg areas of India, the concept of a third sex has been well established, those in such communities often find transsexualism to be strange yet accept the idea loosely described by eg "male body female mind".

So, I'd be interested in that pointer, that shows acting out genital removal is not "aberrant". Does the research also show it's not mental illness to want to become deaf, an amputee, etc.?

Direct me to one of your previous discussions if you like.
