In my most humble opinion, a very little WORKING dick is better then no Working dick at all. If hubby is still a man, not some "I wanna be a woman" trans, he's gonna want to keep his little tiny dick, no matter how useless it is for satisfying women.
This just bogles the mind that a real man would even consider such a venture. Again, I'm talking about a real man, not the alternative stuff out here. A cuckold's journey may not not be an easy one, but he's not so miserable as to consider such an extreme measure.
Why not a chastity belt/device?
Peace
