Ejaculate distance on the moon

But if it’s ejecting from a pressurised environment to a vacuum, it will have a lot more thrust due to the differences in pressure, wouldn’t it? I mean, if you poke a hole in a spacesuit, the air gushes out. I think the effect will be greater than that due to lower gravity.

I think the only way to tackle(!) this question is to introduce magic so as to ignore the effects of vacuum on the human body and frame it in one of two ways:

Either:
Under lunar gravity, and with no atmospheric resistance, how far would a small jet of fluid travel, assuming it is launched with sufficient velocity that on Earth, would carry it a maximum of 5 metres.

Or:
As above, but assume a higher initial velocity due to being launched at essentially a greater pressure - that is, the additional pressure differential between the astronaut’s environment and vacuum (I don’t think astronauts’ environments are pressurised to a full atmosphere anyway).

Wouldn’t the second condition be like an enormous penis pump?

I wouldn’t know - that sort of thing isn’t my bag, baby.

Google says the average ejaculation goes at 28 mph. If we assume a penis 80 cm above the lunar surface, pointed 45° upward, I get about 98 meters.

End zone to end zone would’ve been my WAG.

In all seriousness, I’d say there’s maybe a 75/25 chance somebody knows this already. That is, there was more than enough room inside the Apollo LM for an essentially long underwear-only wearing astronaut to have, ah, yanked one out for fun & science & the greater glory of capitalism!

Giving that these guys were mostly fighter jocks & test pilots, one the one hand I can see at least one of them maybe going for it. But on the other, I can see it being more than a little too homo-erotic for them too. :eek:

“All right, guys, own up. Who got splooge all over my flight controls ? I can’t believe this ! I go for one little moon walk and already you’re behaving like monkeys in space.”

Didn’t a Soviet flight have two astronauts do it for the sake of the nation?
