it sounds silly but I have a question/proposal related to penis anatomy .
I read in many documents that there’s a muscular layer between CC and tunica . Its role is to relax the CC to allow blood to fill the chambers . What if we stimulate this layer ? Could we achieve muscular ipertrophy like in body building ? I ever heard the phrase “If the dick was a muscle we would be all at the gym” .
What if it was true ? : D
