Gains stopping and starting

My gains stopped some time back, so I decided to stop being so obsessive about measuring daily (I know, I know) :) Anyways, is there a great number of people who went through dry spells of gains, and then the gains started up again. I really dont get this because I dont understand why cells in the penis would respond to stimuli all of a sudden. All responses appreciated, cut or uncut, doesnt matter. :D

Maybe dicks are moody? ..

I think this is due to your cock building up tolerance to your exercises and the only way to battle this is to change your routine or stop and let it heal for a while.

Maybe. :)
