Since it hypothetical ...
I would want to experience Everything I could as a woman during my 24 hours as I considered the future.
I would find my toys and explore my new self. Then I'd dress my best and revel in not having to wear any forms or padding or a wig or shave before doing my makeup.
I go out with my head held high and without any concern. I'd be able to at last not be concerned with others staring and hopefully I'd be attractive enough that they would stare for the Right Reasons.
I'd find some young buck and ... well you know.
I'd find a lady of like mind and ... well you know.

Then I would go home and spend the last few waking hours discussing this with my wife. Since all that has changed is me she would have to be on board with this being permanent as well. Then having made my decision I would eat a Big bowl of ice cream, slip into my sexiest nightie, enjoy the rest of the night with the love of my life.

I hope this isn't too...
Mods, if it is, well then do your thing.

But she asked, LOL.
