When I was in Korea for the first time, in our early 30's, we went to the fish market and a older lady who sold weird sea creatures sold us some of them and at the end she took one of those penis fish and gently pressed on it so it would squirt out some water from the front and then she laughed her ass of seeing us so uncomfortable :D
