If it's underwater, wouldn't the cum not travel down the shaft like that?

I really don't want to

Congratulations, you made me google the density of human semen; I hope you're proud of yourself.

It is approximately the same density as water, so it would definitely mix around from the activity, yes.

Danbooru.

I've probably learned more things here then when I was in school.

Good job. Now I learnt something I never even thought about.

I said it before and I will say it again: Danbooru, more than meets the eyes. Always help you learn something new when least expected.

Makes sense, semen (like pretty much all bodily fluids) is mainly water.

Also, it's something that would be easy to test, even without Gollgagh's googling.
