Honestly, I’ve never talked to my neighbors about our sex life.
It is important for parents to teach their kids about the Church through words and examples and caidid conversations.
When our son was around 12 he came home from a friend’s house, that mom told me somehow vasectomies came up in conversation. Our son proceeded to give the medical details in an accurate manner and followed with “and it is a serious sin”.
He knew about how the human reproductive system worked for men and women, the basics of STM and mucous only methods (this was before tech was involved).
That is how things change, parents who are not timid when instructiing their kids.
Being timid, as you put it, about instructing one’s children in sexual matters, is not an option anymore. It never really was. I have to think that a misguided
pudor in not discussing these matters led to many self-doubts, hang-ups, undiscussed and worrisome fears about oneself, and yes, even pregnancies.
My son knows pretty much everything there is to know, in that throughout recent years, he has asked questions — you name it! — and I have always answered age-appropriately and with a vigorous defense of traditional Catholic morality. Just today, we were discussing the presidential campaign, and he has been hearing about certain candidates being “pro-choice”. He asked me about being opposed to abortion, but allowing others to have a free choice in the matter, and if this was a permissible stance to take. I told him that this would be fine,
if it weren’t a matter of human life being at stake, then I illustrated this by asking him how it would be if, for instance, 60 percent of all Americans believed that it was okay to bring home a child from the hospital after being born, and then have the option to kill that child if they so desired. He understood entirely. It’s a gruesome way to have to describe it, but if we believe that abortion is murder — as we, being Catholics, do believe —
then what other way is there to look at it?
