Transitioning doesn't mean they are homo. It means they feel they were born the wrong sex. There's a difference.
Most couples that go through this don't last, unless both parties feel they were born the wrong sex.
And it doesn't matter who thinks what or who does what, or what they consider themselves. It's a LOT of mental work to adjust your psyche to such a huge event. Most people can't handle it, just like they can't handle marriage......and get divorced within a few years, simply because they cannot fathom having to change THEIR way of thinking to incorporate another way as well.
Actual, real homosexual men will not even think about a relationship of any kind with someone who claims to be a "woman trapped in a mans body" or going through "the change", as they are men who like men..........period.
