If it means touching yourself while maintaining an erection, that is one thing, if it mean discharging fluid at a certain rate during th whole time (say a certain volume very quarter of an hour) that is different.  I would personally say if there was a contest for women, I would be happy to be the judge if the criterion was maintaining a certain flow of vaginal fluid that was of a certain consistency and tastes. (Purely in the interest of science.)

Re: How long could you go? Masturbation record holder goes 9hr +

Seldom do so, but once I'm aroused to that level, about 1 minute. I probably could go longer, but what's the point? And, no, I'm not going to go into training to compete.

Who ever thought a room full of masturbating folks would look this... normal??

but I can't imagine masturbating for more than 5 or 10 minutes.

I could win that one...

Without really trying I've masturbated for 5 or 6 hours. If you practice tantra its not hard at all... you get right to the edge of orgasm, and ride the wave. This is why a 1 or 2 hour session always seems a bit insufficient to me. Darn that $ thing.

If he only got one nut off than this is a tragic story.  A much more worthy record would the number of nuts busted in 12 hours. I've probably done 6 in my teens.
