I am rock hard in all my erect pics, HM, I assure you. Getting rock hard is not a problem for me, I'm still young and relatively healthy. My (poorly argued) point was just that when I'm just alone jackin it... I don't always get rock hard, as I don't really have to. And I agree with the people that have mentioned this - soft erections are more about excessive girth, not excessive length.
Also, for some reason all the outrageous claims in this thread not being backed up with any sort of proof are really annoying me, something that usually doesn't happen to me... strange. Is pointing a camera at your crotch really that difficult?
