I so know this story. And as you say, no it’s not OK. But, then if the prevention is children, the mere uncovered penetration, such an ugly word, is grounds for a potential birth. If you love someone, you wouldn’t make love to them. You’d leave them alone unless you had several million dollars and probably much more than that because having children changes everything. Basically, most men are unqualified to have unprotected, another strange word, sex. Just think too of the effect on the environment. We don’t need more children.
