So, I had been with other guys before this, but one guy would pull out, grab the head of his penis right as he was finishing, and pinch off the opening (think pinching a hose so the water stops)… He'd run to the bathroom and let it go in to the toilet. Almost every time. For 6 years.

I didn't realize this wasn't a common thing until I was talking to a couple guy friends about it and they bursted out laughing.
