No- it is interesting jane. I am always up for an interesting discussion- and find it very sad that some at times turn a discussion into an argument. It really does not have to- we can agree to disagree, exchange, debate- and sometimes see each other's point of view- and sometimes continue to disagree, and that is fine.
As said, all 3 cases I know are so different- 1 is young and you would never ever guess, one is now early 50s and it is quite obvious, although she is officially a woman and lives and dresses like a woman, and the 3rd left it too late, and is still very much a man officially and physically, but not emotionally, psychologically and chooses to be sexually active.
