There's post-op prosthetics for ftm trans. You don't even have to transition to use one! I think one of them lets you feel stimulation too. There's lots of goodies that the label peddlers don't tell you lol. And they're good size too!

Before you commit.....which can take as long as you decide to......have some fun with going back in forth, literally! Then as you experiment you'll end up learning more about yourself.
