It can be argued, from a scientific standpoint, that sodomy is unnatural. Unlike the vagina, there are no additional protections against STD’s in the keister. It’s not something nature has even considered, therefore. I would go farther and say that not only is homosexuality unnatural, it is in opposition to nature. That is why, for example, homosexuals are so often in opposition to nature’s God. I refuse to call them gay anymore. They are either homosexuals or somomites, the plain truth. The term “gay” was usurped by them to describe themselves as something that they’re not. I don’t find them to be “happy”. To me they seem angry and depressed most of the time.
Makes as much sense as trying to carrot sticks in your ear.
Doesn't matter whether it's gay or straight couples doing it, either. An anus is not the kosher place to stick it.
