Are rest days required when using ADS, or Penis Extender
I heard that “It is during the rest day that your penis does it’s growing”. Does this apply to ADS and penis extenders as well? People usually talk about rest days when they do jelq exercises or manual stretches, but they never talk about rest days when they use an ADS or penis extender. If penis grows during rest periods then I can only assume this apply to any kind of penis enlargement method?
