It’s both. The General Adaptation Syndrome in humans states that it requires a given stress to make an adaptation to that stress which equals growth in our case. But, it also requires that we either increase the amount of stress over time if we are doing the same type of thing, or change the type of stress to force a new adaptation.
I think I may know where you are going with this, so just keep in mind that regardless of the type of stress we apply to the penile tissues, they will all eventually need to increase to bring about further growth. I am writing up a fairly long post that deals with this and some other stuff, so feel free to chime in with your idea for a routine :)
