>>12067791With an ejaculate specific impulse of 1.27 seconds, you would need a mass ratio of over 1.8e305. Assuming your dry mass is the average human male mass of 87.6 kg, that would mean the propellant mass would be 1.61e307 kg. Which is over 1e254 times more than the total mass of the observable universe.
Taking ejaculate density of 1000 kg/m3, the total volume required to store the propellant would be 1.61e304 m3. Split between two spheres would result in the diameter of just one of those to be 2.49e101 m, or 2.63e85 lightyears (note that the observable universe is 9.3e10 lightyears in diameter.
So in order to ejaculate into orbit, you would need more cum that there ever is in the universe with testicles that are so large that they can store multiple universes into them. The mere act of orgasm would be so vast that it would be impossible for a human to perceive it in his or her lifetime.
