Probably just “regular” mammals.
Mammals have a lot of weird dick things. Some bats have gone from penetrative sex back to just like touching genitals because their dicks are so huge they literally don’t fit anymore.

So having a impractically huge dick was more important for some reason.
Guess something similar happened with hyenas vis-a-vis having become matriarchal at some point.

Majority of male hyenas had a docking fetish, and evolution facilitated their needs.
