neovaginas can get wet naturally
a neophallus can get erect with an implant (this will either be a bendable rod or a device that inflates with saline at the press of a button, usually in the testicles)
both can feel sexual pleasure and experience orgasm
most neovaginas will be able to tolerate larger insertions with enough dilating/training
the nerves in neophalluses take a while to regrow but it is incredibly rare to experience no sexual nerve growth
both can look and feel "normal" if that's what you want, just take good care of your scars and look at your surgeons' results portfolio (and don't be afraid to be picky! its your genitals, you get to decide!)
in fact it's possible for many people to stealth and for their sexual partners to never know. even for phallo, some people with natal penises have erectile implants too, ED is common. neocaginas are often indistinguishable from natal vaginas
many surgeons are starting to offer preservation options for patients who want a more mixed look/don't want to lose what they have
YOU HAVE OPTIONS! demystify bottom surgery
you can also have nothing, if you want!! nullification is starting to become available alongside vaginoplasty and phalloplasty
you can have nothing and retain sexual function, even! it's called nerve-preserving nullification. similarly to other bottom surgeries, they use the most sensitive tissue (glans/clit) to create a subdermal pseudoclitoris
yes you can pee like normal. urethral reroute leaves a small hole at the perineum (taint)
all the advice about scars from OP applies here too!! take care of yourself well and it can heal well
(also, for people interested in the "mixed look" OP mentioned: the magic words are "penile-preserving vaginoplasty"/"phalloplasty without vaginectomy"!!)
As someone who has had nullification done, my inbox is always open.
