MrR and I have only evern been with each other, we did use some birth control early on in our marriage (when we were still in college) but never had to worry if it failed because we were married. We never worried about STD, or anything else like that.
The concept of ‘get married, stay faithful’ is lost on people.
and nowadays getting married has zero upside for men. everything is so adversarial and women are conditioned to always compete with men, husbands have to ask permission to pee in their own house.
