Since I have been on hormone therapy ( yes, I am one of the unlucky ones who made it to metastatic ) most all of my body hair is gone, except down there where I wish it was gone. I can use an old Man Groomer to shave the hair above the genitals, but shaving right on the penis or especially the testicles is terrifying. I've clipped myself too many times down there and just won't do it anymore. I still have mild stress incontinence, probably because of the hormone treatments, and I just can't stay as clean as I would like throughout the day.
Plus my testicles are very sensitive. A mild touch can feel like a hard punch, so as much as I would like to try and shave the testies, I've given up trying.
