OMG, some poor dude in India underwent emergency surgery after his three week, yes, three week, erection just wouldn’t go away. Doctors said if they hadn’t performed the surgery to put him out of his misery, he would have died. As it is he is now impotent. The man was suffering from a condition called priapism where blood is prevented from draining out of the penis. If not treated the penis becomes gangrenous and/or withers away.
