Ok don't laugh this is a serious question. When I do intense exercise (Judo, BJJ, muay thai) and go to the changeroom I notice my flaccid size becomes extremely small compared to normal. I heard AAs and high blood pressure can contribute to this. Also when you exercise the body takes all the blood to the other parts of the body, I am 6'5 and 250+ pounds so this is understandable. But the thing is this doesnt seem to effect many of the other guys...Any takes on this?
