After going back and forth on this a lot, I am starting to see the picture. I figure I am probably aout 40% female and 60% male. Or maybe it's 50-50, or maybe 60-40. The numbers don't matter. What matters is there's some of each in me. "Genderfluid", I guess that's called.
After spending 60 years trying without success to deny the female part, I can see that it would be a mistake to turn around and try to deny the male part. I'm both. Always have been, always will be.
Most likely, this will mean no transition for me. A bit of me is sad about that, but it feels more real this way. On the plus side, it makes it more likely that I could eventually come out to my wife without the whole idea being rejected out of hand.
What I see as a viable future for me would be to be able to cross-dress openly at home or with close friends.
I am going to sit with this idea for a while to see how it fits. So far, it feels like the fit is good.
