the big question we should be asking is
what about the weenis, will you still be able to jack off to your wacky special interest research
Yes. HRT does lower your love drive, and it crashes completely for a few months at first, but I'll still be able to get off and many girls going on HRT describe their climaxs as more "female" after a while. And if I do end up getting bottom surgery in the future, yes, it'll all still work as you'd expect a vagina to (minus the whole reproduction thing).
You usually lose your libido after starting HRT.
At first yes, but from what I've heard, it tends to come back in a more feminine way after the initial few months.
