Small-Scale Question Sunday for November 8, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

IIRC there’s a bunch of nerve endings down there. That kicks the can down the road, but my (uninformed) guess is that evolutionary biology has a lot to do with weird compromises from millions of years ago. Did our synapsid ancestors still have a cloaca?

Do other female mammals find the act of penetration itself during estrus pleasurable? Or is it more about getting rid of the distressing psychological urge to copulate?

Some primitive mammals have a cloaca, so I would assume so.
