As a man, I started shaving down there after a woman forcefully assaulted me. I also prefer at least a trim on my partner. It feels unclean to have a full bush, but I recognize that is a traumatic response.
This also happened in the mid 00s when it was becoming a thing. I also note that the body odor is considerably less that having hairy pubes. (Same with armpits.)
I wonder how many of those videos were actually a human watching vs a machine calling the api, and how long did they watch for?
