Does the neo-vagina get wet and auto-lubricates itself like the bio-woman vagina?

it produces the same stuff in there, but there will be less glands so there wont be alot of it
most will have to use lub

the colon method is a "always on" state, sometimes it produces too much but the newer methods somehow reduced it a little so there isn't a need for a pad

You will likely find that you will need to add supplemental lubrication no matter which surgeon you go to.
