At about 9 months into my HRT, I had lost most erection ability, but one night I had a wet dream, and part of the dream was somebody trying to castrate me without benefit of anesthetic. That was the last time I ever became erect, but the memory still makes me turn white as a ghost. I had actually let out a shriek of pain. After that time I would get some fluid discharge with a Girl O, but ugh!!
With Dr. Bowers I did not go completely off of Estrogen, but did have to cut off the Spiro two weeks before surgery, and I could feel some "old" sensation, but I was too damn crabby to feel like any masturbation, and too tired running around to get ready for the trip up north.
