In high school we were told that they believe female sea otters are only receptive if they're in pain and almost all females have scarred muzzles a result.
Also something like 75% of orangutan copulations involve the female resisting.
Just googled orangutan rape to try and get a better number. Found sources claiming that 1) orangs will occasionally rape human females 2) female orangutans will be used as prostitutes in brothels. Dear world please don't let either of these be true.
they should do this all over the world. it would reduce human rapes and sexual assaults significantly, i would run the classiest orangutan brother around..
I read something a while back about an orangutan being saved from a brothel where it had been held captivated for several years as a sex slave... the world is such a fucked up place, and I dont want any part of it.
