times....or hours I guess
At MSU, many years ago, some friends had a serious contest as to see how many times they could jerk it off in an hour. They each had a paper plate with a pen drawing out 8 equal sections on each, drawn out and judged by females. I think there was either $50 or $100 in the pot among 5 guys. The guy who won wacked it 6 times in one hour, where I think there was 1 guy who got it 5 times, and another 4.
I think the guy who did it 6 times in one hour (every 10 minutes) probably was on some performance enhancers.
