I realize you were just making an analogy, but the two scenarios are definitely different. A better analogy, albeit argueing for the other side of the argument, would be that overbuilding you pectoral muscles will cause your shoulders to roll forward and pronate the hands. When you flex your PC muscles, you will notice your penis retracting. If you tone this muscle too much, I can certainly see the possibility (far short of being official) of causing a semi-permanent retraction of the penis simply due to the muscle growing in size. The retraction would be very small however if it did, so I wouldn't neglect PC training if you feel it is helping you in other ways.Threak-X;279271 said:If I do muscle contractons on my biceps and triceps my arms will shrink as well.
