I met my first Master when I was 20 and had a 9'' cock. After a period of getting used to it, I was consistently locked up by him for more than 5 years. After a few months, I got an erection less and less often during the cleaning sessions and at some point my cock no longer got hard at all. My next Master continued to consistently lock me in smaller and smaller chastity belts, at the same time he tortured my balls more and more extremely. After a total of about 7 years, I no longer got an erection even after a long time without a chastity belt. This is still the case today. My cock gradually shrank from an initial 9'' to a flabby 4'' and after almost 30 years of constant chastity it has shrunk to less than 2''
