My significant other is in the medical profession and things Jenner suffers from addictions to plastic surgery and is not a classic “trans” gay type. Michael Jackson was like that too, etc. Turning trans was like the ultimate plastic surgery make-over and that was what attracted Jenner t o it maybe more than the “woman in man’s body” BS.
I also think Jenner suffered from being around the Kardashians too long - that would drive any one nuts.
