[Game of Thrones]So do Unsullied still have dicks and no testicles? Or nothing at all?

And if they still have a dick can it get hard?

Edit: Awesome thanks guys! Show has the dick, book has the ken doll.

In the book series, they are cut completely, with no outward male genitalia left. This is in contrast to normal eunuchs who have their testicles removed.  Their manhoods are burned on an altar.

Furthermore, Unsullied drink 'the elixir of courage' which deadens their nerve endings and makes them feel little to no pain.  This is demonstrated in front of Dany by one of the slave masters cutting a nipple from a motionless Unsullied who does not react.

If you want to get even more messed up, on the day that the Unsullied boy is cut, he is given a puppy to take care of.  After a year, he is made to strangle that puppy and kill it.  If he is unable, he is skinned and fed to the remaining dogs.

I wouldn't be surprised if this is not the case in the show so that they can have the Grey Worm romance which does not exist in the books (as Missandei is like, eight).
