Yea for shrinkage down stairs, the best phrase comes to mind. You lose what you don't use. The less you use it, and or allow it to to fully get erect the more you will shrink in size (length and girth), as well as ability to be as firm as before. No using in conjunction with no or hrt will increase that dramatically. 

Maybe try considering using a chastity cage, but then again that's a completely different rabbit hole to go down... And def not one this forum is built for lol.
