Does anyone know what kind of effect this has on muscle gain? Like say if i was only to use one arm the whole time would that arm be bigger than the other significantly? Or does maturbating not have an effect on muscle growth?
depends on what angles, strokes and approaches you are taking.
for instance, if you have your leg up on the sink and are reaching around back up and under your leg pulling your pud back down towards the floor using more of a downward tug, it can probalby also hit your tricep bro. good luck.
my technique is just short of a masterpiec, sumthing short of an aggassi backstroke, u know, hard and fast, u really cant teach it, but i get wicked mad pumps all over my arm.
