In the days before the internet you could buy these glossy mags that reviewed adult films. I read in one that Peter North (gay and straight actor but at that time straight) was in a movie (forget the name) and spasmed 14 times in a row with a good load each time. I didn't believe it. Later I was able to rent the movie (vhs) and it was true. Better that true. Like the first ten shots were huge. the next two were respectable. the last two were pretty nice. I counted...14.
