I heard a doctor on the radio explain how male/male sex is unhealthy for many physical reasons. I can't describe the physiology of it, but he explained how the rectum is not suited to receiving a male penis. It is meant to expel excriment from the body. He also explained that male sex drive combined with another male sex drive equals disaster as far as disease is concerned.
Yes, and because it's designed, as you say, for 'expulsion,' it's very easily torn and traumatized by what homosexual males do to each other. And then the tears become infected with the toxic bacteria that exists in that part of the body and whose purpose is to rid the body of waste. Result: blood-borne disease and all sorts of other horrible consequences.
