Did,nt say I was a doctor but the bloods gotta go somewhere right!?:wink:
There is only so much blood pumping around or am I wrong?
I'm no medical expert, but haven't you ever donated blood?
Average adult has 10 pints of blood. Usual donation is a pint. The biggest erect penis holds nowhere near 10% of the blood mass or however you want to look at it.
Sure, a few people do pass out after giving blood, but they must have poor circulation to begin with.
Plenty of blood is still flowing through the rest of the body.
It would have to be an erection bigger than your leg and I think that would be plenty more painful than pleasurable to achieve.
Even if my science is wrong, a giant boner isn't going to cause it's owner to pass out.
