Rest and recovery time?
How should I be able to decide when I need rest days?
I usually go by how my body feels etc but what are the tell tale signs that I need to let my penis recover? When I feel smaller than normal? If it were to go red? What are the signs everyone looks out for?
Also when its a rest day should I completely leave it recover EG no sex, masturbation ? Or will that not greatly effect my gains?
