No, it does not! OLVS is very traditional (Latin Mass) and I'm sure none of the other Catholic programs (Seton, Mother of Divine Grace, Kolbe) teach "sex ed" as we tend to think of it, either. I know Mother of Divine Grace has one of JPll's encyclicals on married love and I recall hearing from a homeschooling friend that one of the Catholic programs was offering an elective in Theology of the Body for teens, but I can't remember which one.
