No.. But it does of course make it more vulnerable to pain since it's erect. Bending it or anything similar can hurt it, but if a man is erect for too long without ejaculation, it causes pain to his genitals.
The cause of an erection is not simply blood flow, but rather INCREASED blood flow. When a man gets aroused, the body increases blood flow to the penis which causes the erection.
