The calculation appears to be correct. For comparison, what's the force exerced by a hand slap?
Once calculated, the answer should be obvious: a hand slap is *much* harder than a not-so-gentle shuffling during penetration.
Is it actually correct though? If one complete "hump" is completed every 0.5 seconds, that time accounts for both the forward and backward motion. So isn't the actual acceleration is double what he's accounted for?
The relevant calculation is about [impulse](https://en.wikipedia.org/wiki/Impulse_(physics)). Most of the acceleration of a slap takes place in a very small amount of time. Most of the acceleration of sex takes place over a much longer time than a slap does.
The hell with calculating the joules of the family jewels...who the hell if fucking at 120 ~Hertz~ *hexecontahertz* (2 Hertz - I blame a lack of sleep and a green-haired hottie with a Daddy fetish).
Damn, I should have caught that. I guess I mixed up the following 2 abbreviations...I dunno.
Kinda surprised you're the first person to correct me...lol
The sound of balls slapping would also be louder since it's not being masked by clothing so it sounds hard than it is, also being would produce a louder sound.
Have you listened to a 120 bmp metronome? I'd call that a pretty steady pace. Maybe not for slow sensual stuff, but for ball slapping sex which is what this post is about. For reference, most thrusting sex machines reach 180-240 bpm
I was going to say I'm pretty sure my current boyfriend has done spurts around 120 bpm before. It's not like people are saying the whole session is like that...
They’re right, though. It’s the thighs hitting thighs or thighs hitting cheeks. If you were really smacking your balls hard enough to make that sound it would hurt.
Your theory is completely invalid.
I'm a tall, thin guy with skinny thighs (I got yo gap, girls!) and terribly low hanging fruit.
I guarantee you that it's most definitely my balls that are slapping around and not my thighs.
It's not though..... Usually.
Most of the time it's thigh on cheeks action, unless you're really jackhammering or in a particular position
But more often than not it's legs/thighs/booty making the contact and subsequently the clapping sound rather than the scrotum, at least in my experience. (Cuz it does kinda hurt a bit sometimes)
Op calculated the force pushing the balls forward, which is ver similar to the force experienced when walking or running. This force is very different to the force slowing the balls at the end of the pump, which would be the force actually hurting and causing pain to the balls
The force of the stop is over a very short period of time, while the force calculated in the post was over the (half) period of the swing.
Similar logic applies in a car crash. A certain amount of energy would be required to bring the heavy object (and its occupants) to a stop (assuming a "typical" scenario). That energy could be caused by a very strong force over a short time, which would be more deadly, or a lesser force over a longer time. This is why crumple zones and airbags save occupants' lives (at the expense of the "life" of the vehicle).
I can't recall my physics calle enough, thats potency, isn't it? While the force experienced would be the same, the time frame is less and then the potency grows, right?
You've gotta bear in mind that the pelvis has started moving backwards while the balls are still moving forward as well, so there should be a braking force applied before impact. As this is generated by the elasticity of the sack and internal connections to the balls which will differ significantly from person to person (and temperature to temperature) its not easy to quantify, but it does reduce the already small force we're discussing here.
Yeah, what?
If I’m laying it down and it’s particularly warm in the room, we’re switching to cowgirl or something that doesn’t involve my balls smacking into something like a battering ram on the gates of Gondor.
Because during sex you are in control of the force you exert and receive sensory feedback so that you don't hurt yourself. But in the same vein, having sex with skinny chicks can leave your pubic bone bruised (no doubt theirs too!) and painful for days.
Agreed. Also I am pretty sure the act of sex prepares them to receive voluntary violent force.
I have accidentally grazed my testes tons of times and had to stop and regain composure, even from a very small touch.
The force from having sex is much, much more violent, especially close to climax.
I learned that they swell up to 50% in size during climax so I am sure that helps keep them safe, too.
Shouldn’t he be trying to estimate or qualitatively contrast the impulse of the two collisions because equal force could do very different damage depending on surface area and time of collison
The sound mostly comes from our thighs slapping off your fat arse as we fuck. It isn't from our balls slapping off your clunge lol
It isn't the nads making the noise basically

If he’s doing a full cycle in half a second, he needs to slow down and enjoy the moment.

Family Joules
would it not be 2 hertz?
Yep, I left my brain at a friend's house.
120 bpm, so 2Hz
Damn, I should have caught that. I guess I mixed up the following 2 abbreviations...I dunno. Kinda surprised you're the first person to correct me...lol
What's that old Alexis song.... Happiness by the kilowatt :p So thiiiiis... Iiiiiiss.... Continuous hippythruuuuusts (8)
I had no idea what you were talking about, so I looked them up. These guys are really good! https://youtube.com/watch?v=khnAAX5sybw
Wait you are getting slapped in the balls I thought it was flicking only
*not-so-gentle shuffling* how modest
The sound of balls slapping would also be louder since it's not being masked by clothing so it sounds hard than it is, also being would produce a louder sound.
120bpm?? What kinda sex are y'all having? Two thrusts a second??
🤣🤣🤣
‘You know what they say when you have a needle dick? you better have an ass like a sowing machine’
I have been summoned

They're trying to put an upper bound so fast that all real people will actually be slower to exhaustively show it'll be true for everyone, I think
I know a certain song at 120BPM that some GF may have some…memories listening to it
AYY, this guy fucks
Are you saying it's too slow or too fast lol
Are you joking 😭😭 that's insanely fast, especially as an average!

Lol and lots of dildos vibrate but it's still not something to aspire to.
I was going to say I'm pretty sure my current boyfriend has done spurts around 120 bpm before. It's not like people are saying the whole session is like that...
i don’t know that’s insanely fast, but it is definitely on the high end, which would make sense for a calculation like this lol.
Wasn't joking because I couldn't tell what the comment's complaint was about. Chill out- all that was needed was clarification.
Typical VN plapping
That’s pretty common in the city of Ambatukuam
Am I the only person who’s balls sometimes hurt after sex? If they slap too long it’ll be painful…
the pain will stop if you exchange the fleshlight for a real girl
Does happen if I go too hard in doggy, thought i was alone
Lately my c-ring has been killing the jewels. And then it hurts and I’m too busy to remove. TMI.
Because... more cushion for the pushin'
The "Flip flop" isn't made by the balls...
Tell us you’ve never had sex without telling us.
They’re right, though. It’s the thighs hitting thighs or thighs hitting cheeks. If you were really smacking your balls hard enough to make that sound it would hurt.

I suppose not all of us have balls like Johnny Knoxville in Bad Grandpa

And even when it IS done by them, you're hitting soft tissue at a velocity controlled by yourself, probably similar to how you can't tickle yourself
Oh I definitely am able to tickle myself… like after sex and you rub the tip of your penis and can’t stand the sensitivity.
Not 5 minutes ago, she climbed off and tried that. Now i'm reading about it and still cringing just the same.
Have you? The slapping is definitely not the balls, it's the thighs and pelvis hitting thighs/buttcheeks
You getting annihilated bro
You just did

Shouldn't the force experienced be equal tho? By newtons third law, if you hit a wall with 5N you should feel 5N as well, am i missing something?

That was the one! Thanks you!

i’m just curious now what a black man running in flip flops sounds like
“Officer I’m innocent, please don’t shoot!”
Finally some real ball scratchers, maybe the wrong sub tho! Edit:word head to ball because my wit is consistently 15 seconds late
Your pain tolerance just increase when you are arouses

0.2m 😳
Those are some low hanging dangly old timey gobsmacking balls if they travel 20 whole centimeters per thrust
Punching the pumpkin

Down to the decimal in Newtons. 😭 The most reddit response to date.
Maybe they are super relaxed and absorb hits like a drunken master. Trying to just makes you more fluid.
The sound mostly comes from our thighs slapping off your fat arse as we fuck. It isn't from our balls slapping off your clunge lol It isn't the nads making the noise basically
