Not really sure what is going on, so I will come up with a summary based on stuff I read.
Ok, so these people aren’t all descended from primates, so some are from other animals. These zoomans are able to interbreed with normal Humans and other zoomans. Well, this one guy must have some awesome junk or something because all the zoomans want him to make a baby with him. Not sure why though. Also, it’s a boys love, so homophobes probably will want to stay away.
Thanks to ANN for the find
