Just keep in mind that those are you views on sex, and you can communicate them to your children, but it is still your children who will decide when and with whom they have sex. Their bodies belong to them, not you. And they get to decide.
And as Donna Martin said "If you have a swimming pool in the backyard, you can tell your kids not to go in, you can put up fences and gates and lock them, but if you know your kids are going to figure out a way to get in, don't you think you ought to teach them how to swim?"
Also, this original post was about our children having sex in our homes which, of course, implies consent and condoning. Oriole (and me, by the way) don't allow our children to have sex in our homes, but that doesn't mean we're going to follow our children around 24/7 making sure they don't have sex.
