In my teens I would spend entire nights beating off over and over to porn. Usually only needed about a 15 minute break in between sessions. I'd say the most in one day back then was around 10 times. I was raw and shooting blanks at about the 3rd time, but it didn't slow down those adolescent hormones!

Now, I'm lucky if I can crank out two in a day. Usually, one and I'm done.
