Didn't watch but I know some things. An erection lasting more than 4 hours can damage the penis permanently. Some bodybuilders use an erection drug called Trimix which is injected into the penis. No big deal they say, just a fine insulin needle you don't even feel. It's for when Viagra fails. But if you have priapism they may need to insert a butterfly catheter or like an 18 gauge needle to drain the penis of blood. That would suck.
