The researchers found that females yelled during 86 percent of all sexual encounters.
When females shouted, males ejaculated 59 percent of the time. However, when females did not holler, males ejaculated less than 2 percent of the time.

To see if yelling resulted from how vigorous the sex was, the scientists counted the number of pelvic thrusts males gave and timed when they happened. They found when shouting occurred, thrusting increased. In other words, hollering led to more vigorous sex.

    This only tempts me to refuse to make any noise whatsoever during sex just so I could see what happens.

    I'd like to, um, see the data.

    You totally tricked me into clicking a link about monkey-sex. Ewwww.

    In other words, the monkeys are not violent guys, but when driven, they will react?

  5. fastfwd says:

    Just to clarify: are these the monkeys with the typewriters who are going to produce the complete works of Shakespeare in a hundred years? Or is this a different group?

    I was just wondering. But now that I think of it, it must be a different group. I doubt these monkeys would care to stop and type for a hundred years...

    • violentbloom says:

      Are you suggesting Shakespeare was a sexually frustrated monkey?

      • fastfwd says:

        No, I'm alluding to the old theory that if a hundred monkeys typed on typewriters for a hundred years, they would end up hammering out the complete works of Shakespeare just by chance.

        But as someone else has pointed out, now that we have the internet, we know that's not true.

        • violentbloom says:

          Yeah I was alluding to the fact the monkeys would need to be sexually frustrated before they'd restort to doing that. You know if they're fucking they're not typing. Not so funny once you have to explain it though.

        Sexually frustrated _ape_.

    "Counting monkey pelvic thrusts is admittedly 'quite weird, but it's science,' researcher Dana Pfefferle, a behavioral scientist and primatologist at the German Primate Center, told LiveScience. 'You get used to it.'"

  7. the other 39% of the time?

  8. Everyone knows that to make a guy really come you have to fake like you're coming too. ;)

    "ook dirty to me"

    I want the scattergram of thrust-rate-before-holler against thrust-rate-after-holler.
