The intention of comparison is, basically, "unnecessary dramatisation".
I suspect Clarity was thinking about unprotected sex with somebody they've already been in a stable monogamous relationship for a while (possibly partly because they want a baby), whereas polymathwannabe was thinking about something more like a one-night stand with a stranger. But if the latter is right, the dramatization ain't that unnecessary, at least in certain geographical locales.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
