Fair enough - it just seemed like an odd blanket statement to make.

I’d be horrified if one of my kids told me they wanted to marry the first person they’d had sex with

I agree with your overall point, and fully endorse a liberal pro-information approach to sex ed in schools, and think that sex is a joyful and a wonderful part of life, but the above statement is depressingly small-minded. What's wrong with marrying the first person you sleep with per se? I'm a little biased because I have done just that - we didn't wait until marriage, we started sleeping together as horny teenage uni students and ended up marrying in our mid-20s after living together for several years. It's not common nowadays, but for some people, including myself, it can be very fulfilling to have one sexual partner for long periods of time and even life. My parents are not consevative moralists of the Family First ilk, they are lefty-liberal hippies who wanted me to be empowered to seek my own happiness and contribute as best I could to the happiness of others in society. So they taught me to go with what I know is right for me, and it so happened that marrying my first sexual partner turned out to be just that. I hope that if your kids happen to fall madly in love with their first sexual partners and decide that their life's happiness is best served by a committed monogomous relationship you will respect their choices. Kinda hypocritical not to.
