I think the need for secrecy would diminish as the kid gets older. By the time they're a teenager they won't be traumatized to learn that their parents are kinky - just kinda grossed out to realize that you're having sex at all. ^_^
Um, I'm way away from teenager-hood and I would be irrevocably traumatized to find out my parents are kinky.
You said it true, Natalie. Grossed-out works.
~shudders at the thought~ Ick.
I'm still such a child. ~sighs~
