Human sexuality is tribal, brutal, wild, and messy. If you wish to make things all pristine and modern with your advanced sensibilities, consider this. We are not even a Type 1 Civilization yet. If you employ the idea of high standards then accept the idea that we have yet to achieve the concept of the minimum level of Civilization, meaning we are STILL in the Stone Age regardless of how much we pat ourselves on the back for all we have accomplished. If you are still subject to death and aging, and when your hand gets chopped off and it doesn’t grow back? Modern Medicine doesn’t exist yet! Standards.
