I know this is kind of a goofy question but bear with me K?............
I was talking to one of my guy friends today and he told me guys ejaculate at 13 miles per hour! I find this hard to believe. Is it true or is this guy just totaly wrong?!

.....and I KNOW I came across yet another speed of ejaculation when I researched some sites for the repro-links....but now I can't find it anymore...Grrrrrrrr......

...let me search....

I think that no matter what statistic comes up in regard to this -- and anyone who can provide DOCUMENTABLE stats on the matter is welcome to do so -- you still have to remember one thing:

People Vary. A Lot.

In my time, I have seen men who ejaculate quickly, slowly, a little at a time, in huge SPLOOT!s, in slow trickles, and everything in between.

So any statistic is, at best, a probability. Not a law of nature. Just a probability that, in some cases, MAY be true.

my head is still aching from my physics midterm. don't make me spit out those calculations again. i screwed them up the first time, anyway.

thisguy! care to use that engineering know-how to expound?

I'd say the best way to estimate is basic kinematics.

Assume an adult male ejaculates while standing. For simplicity, the fluid is expelled horizontally.

Now, the fluid - whether dropped or expelled - takes a set time to fall to the ground. (Neglecting aerodynamics)

z = 0.5 X g X t^2
where:
z = the distance fallen
g = the acceleration due to gravity at sea level. 9.81m/s^2, or around 32ft/s^2
t = the time taken to fall.

For a set time, the fluid will travel a set distance horizontally. This distance is linearly proportional to the initial velocity.
x = u X t
where:
x = the distance travelled horizontally.
u = the velocity component in the x direction.
t = time.

Now, if you solve both equations for t, and equate them, you have a relation between the distance fallen, the distance travelled, and the initial velocity.

2z/g = (x/u)^2

OR

z X x^-2 = 0.5 X g X u^-2

As a rough guess for the two distances, x = 1m, and z = 90cm.

4.905/0.90 = u^2
u is roughly 2.3m/s, or 8.3km/h, or 5.2mph.

I am utterly sad.

Sometimes I ask myself: "Self, what's life all about?"
But I never reply. I'm rude like that.

YAY ThisGuy!

What a studly display of geekliness. It made me grin from ear to ear, and believe me, this morning, that's saying something.

What? I dont understand?? Sheesh, Im glad Im going to be done with math next year......HOLY SHMOLY!!

ThisGuy your posts always crack me up!!!
u way have a way of making your point hit home...albeit shrouded in a huge dose of your own peculiar brand of humour

here's another way of looking at it...correct me if i am wrong ok?
in terms of momentum...
a speed of 13mph is appr= 8 meters per sec
lets say that the vol of sperm ejaculated is appr= 5cm cubed
mass of this is approx = 5 grams
force exerted by this lets say in a womans vagina=change in momentum divided by time taken to do so
if time taken is approx=0.1 sec
now this is time for fluid to hit hte walls and bounce off and not necessarily the time taken for ejacultion to cease
force= (2 x 8 x .005 )/.1=0.8 N
which is equivalent to a mass off 80g
hmmmmmm
imagine that mass hitting u?
i dont think so.....at least i hoep not!!
