Much of his life he has isolated himself which isn't unusual for those in the limelight as he was. ..it goes with stardom, especially for those who have personalities which value their privacy.... But 'at the same time', and for Jenner, there's an exhibitionist twerk they also contend with and need the public "attention"....which often goes along with those having sexual deviant issues.
... So there's more than just a few issues Jenner hasn't worked through. Therefore going public as he has is not going to bring the results he's imagined might be. He says he can take it...but clearly contradicts himself often..... If you listen to him you see he's not adjusting to what he thinks he is. ...He KNOWS he's not a woman, neither inside nor out, regardless of the garb he's using to play the role or what he says.....which cannot change the reality he is a man with mental issues of how he 'thinks' and what he desires.
I had the occasion to be waited on by a male body builder who has Jenner's issues. Let me tell you there's a reason they are seen as 'Freaks"...it was one of the most bizarre and freakish encounters I've had...couldn't wait to get out of the store! My discomfort level was off the scale as the sight went against everything "natural" including his behavior which no woman would have exhibited.
