4094 divided by 2 is 2047 male anscestors. The average volume of semen per ejaculation is roughly 3 mL on average.
2047 x 3 is 6141 mL of cum or 6.14 L of cum or about a gallon and a half.
The average fuel efficiency for cars in the US (sorry Europeans) is 25 mpg. This means if cum had the same energy density as gasoline you could travel roughly 37.5 miles on all the cum your male anscestors produced in the last 400 years.
That’s only one ejaculation per male ancestor. You can safely assume that the average male ancestor ejaculated more than once. This would increase the distance traveled using the cum energy.
