Multiple reasons. First apes are stronger than man, so they can rip your dick off easily, they have strong bite as well, so it is dangerous to attempt if you are not 100% sure the ape is into it. Second, they have small pussy, so penetration would be uncomfortable for the female ape, if not straight up painful, unless you have a micro penis. And if you hurt her, see the first reason what can easily happen.
Male ape and human female can be a thing, but it is also hard to orient a male ape to fuck a female human, because of the lack of scent. Teaching them could work, but who has the money and the time to own and train an ape to fuck human females, or train to let be fucked by men.
I know a "maybe not fake news" story where a female orangutan was trained as a prostitute on Thailand maybe. But police shut that brothel down as it was super illegal. The news said that the orangutan was used more than any human females in that brothel.
