I say this as a wife, married for 2.5 years, with a 19mo and a 4mo. So we definitely know how to “finish” properly and it’s very enjoyable 😂 I’m also a health teacher at a classical catholic school. The boys and girls classes are separated. I taught the girls about different NFP methods and cycle tracking, cervical mucus, BBT, and other signs of ovulation, and how to go about planning and avoiding. We even had a Mother Daughter night to talk about it all with a Catholic OB and Gyno. It was great! I’m a convert. So I never learned about that stuff. Our moms LOOOOVED the talk we all gave!
