The dirty secret of birth control is that it doesn’t work. That’s why gals who use it are the bread and butter of the abortion industry. That’s also why abortion providers market contraceptives and “sex education.”
In my experience, it works if you use it correctly.
My wife and I have been married for 30 years. We were fortunate to never have any fertility problems even though we waited several years to have any children. When we wanted children we had them. When we did not want children we did not.
We no longer have any need for birth control thanks to my wife's menopause. We are now having to buy it anyway thanks to Obamacare.
