You are either trying to misrepresent and demonize, or your comprehension skills are a bit lacking. Instinct tells me the first is true. Your so called "can of worms" is hardly an issue as well. For the record the article reads as follows, ""Sex among dwarf chimpanzees is in fact the business of the whole family, and the cute little ones often lend a helping hand when they engage in oral sex with each other." Okay that sounds totally different from what you wrote. Now let's add some common sense to this and see what we come up with. We know that non-human animals mature at a far greater rate than humans. We know that mating in non-human animals happens out in the open with no shame for the whole group to see. We also know that humans often engage in sexual experimentation at an early age. When was the first time you kissed someone that was not out of family greetings and goodbyes? It would seem that the problem here is your perception and representation. Nice job!
