Cumming in ice cold water, then playing with congealed cum

Have you ever done this? I've cum in a glass before and then drank it but never done this sort of thing before. This is what the guy who did this said:

I filled a container with ice cold water from the fridge on one of the hottest, most humid days of the year and plunged my cock into the super-cold water as I pumped out 8 clouds of hot spunk. After stirring the resulting mixture with my finger, I pulled out a strange white, rubbery mass and played with it a bit. One of the weirdest things I've ever done. (There was a big splash as I spilled some water trying to get the right angle, but you can't hear it much on the video.)
