I love what HRT does to a (formerly) male penis. It's so hot how the testies stop being useful for anything and shrink back up against her body leaving that cute little sac, and the penis atrophies from lack of any purpose or use becoming a flaccid, inch long appendage. Never able to achieve erection again and, when played with, her feminized "penis" only produces "girl cum" as this shemale calls it. Now, the completely sterile, shrunken and feminized penis can't even be considered a cock, dick or really even a penis anymore, just a useless little clitty or toy that real men can lick and grab when they they fuck her in her hole. Beautiful emasculation.
