A lot of furry troons, I'd say an extremely high percentage, eventually don't get the surgery. They may talk about in the few years where they're highballing on the transition high, but they either remember their penis works, or they just call their transition good enough when it gets too much to really maintain/talk about. A lot were very horny guys, and will go into completely as a fetish, and Dave fits that bill.
However there are some that go full blown and do the deal, and Dave might just have the cult group assistance, and insanity that will make him able to keep things together. I doubt it though.
