Why would either insurance-based healthcare (as obtains the the US), or public, free at the point of use healthcare (as obtains in the UK), consider it a viable use of funds to bolster some kind of sexual kink (operating under the assumption that AGP is even actually a thing)? It seems to me that a different sort of therapy would be on offer for such outlier cases.
Also, I think it has been mentioned, that those who are designated AGP often do not persist with HRT treatment, as such treatment effectively nukes the libido/sex-drive, thereby defeating the object of the exercise?
