I think what he means is that fluids are sucked faster than blood, so the faster you pump, the more fluids and less blood you suck. If you have skin stretch marks, that could be an indicator consistent with that hypothesis. I guess skin is more elastic than tunica (expecially when the penis is erect), so if the expansion was due to blood inside the tunica, you should have scars on your tunica. Not something to aim for.
