Since somebody brought up split roosters and other rooster talk
what happens in you piss and spoof at the same time?
It's incredibly difficult to do so.
When you get aroused as a male, your p-spot pretty much kicks in and blocks off your bladder.
It's a lot less comfortable to have a hardon and have a bladder full of piss at the same time but it's really impossible to piss and bust a nut at the same time.
