Not really, they would just rather keep them then have a fake pussy and no orgasms

XY chromosone hormones would
They get suppressed so its the luck of the draw and the amount given can also vary alot along with the type.
Yer I dont think anyone who keeps their cock and balls are transgender. They are the same gender even in their own eyes.

Good question. I would think regardless of the female hormone replacement treatment's that Bruce's own natural XY chromosone hormones would still once in a while or even occasionally still cause111c an erection to stimuli.
I don't imagine XX female hormones cancels out the XY all together, on the other hand if his penius was sliced and pushed inside to create and cover a vaginal wall opening then no, no more erections or getting it up as it would be split and tucked away internally.
TranZgenders are kinky and sly that way, they love playing with their big tit implant's, taking it in the ass but still love playing with their cocks too.
Suppose that's why plenty of them opt not to have a vaginal implant done. Instead of being a guy flogging his log they become chicks with dicks or cocks in frocks.
Best of both worlds and bizzarro penthouse play mates.
Nothing is as it seems, nothing is just one thing and nothing is ever just over there;
