The overwhelming norm is for a man to put his 1 into a woman’s 0. This was decided by Natural Selection a very long time ago. Back in the day it required a 1 and 0 for a human to reproduce themselves. Today that seems to be a lesser requirement but the rub in all of this was religion imposing a 1 and 0 standard only with everything else being considered abnormal!
Ironic perhaps because in some religions their leaders were precluded from sticking their 1 anywhere as they were married to their fictional god. Now that is what we would call abnormal and at the end of the day what adults do with their ones and twos behind closed doors is their own business.
And that is all I’m going to say about that.
