I just don't get...

(Apropos various conversations on various blogs over the past few months) I just don't get why some adults think children must be completely shielded from any sight, sound, or discussion of anything related to sex. Well, actually, I get it if they're talking about postpubescent children, who might (shock! horror!) want to try it themselves. I think they're wrong, but I can comprehend their position.

What I really don't get is the panic at the thought of a prepubescent child having any idea that adults have sex. For them, it's going to be another thing that adults enjoy for no apparent reason, like drinking coffee. I mean, if I ever have children, I fully anticipate having to have this conversation at some point:

CHILD: What were those noises coming from the bedroom last night?
ME: Oh, er, Mommy and I were having sex.
CHILD: What's sex?
ME: It's a thing grownups like to do. It's like kissing, only with your entire body, and it takes longer, and sometimes we make funny noises while we're doing it.
CHILD: Eww, gross!
ME: Trust me, grownups like it. It'll make more sense when you're older.

And probably no more need be said until it does start making more sense. Mind you, I agree that the Folsom Street Fair and similar are not appropriate activities for small children — but it's because I am certain they would be bored.

CHILD: Why is that man wearing that?
ME: He thinks he looks good in it.
CHILD: Isn't he cold?
ME: Probably.
CHILD: Can we go to the park now?
