I would answer my kid's question with age appropriate answers, treating it matter of factly. No big deal, just a simple response. They're going to learn it, might as well be from you so you can make sure they have the correct understanding. It was pretty embarrassing to find out my 'china' was really a vagina, that 'administration' was menstruation.
What's a virgin? A woman who hasn't had sex/made love/ etc. I remember while reviewing the 10 Commandments in CCD, the kids asked me what adultery was. They were probably in fourth or fifth grade. That was fun. "Imagine a Mr. Smith wanting to that 'married stuff' with someone other than Mrs. Smith." I made an icky face and the kids said.. Ewwwww. Little did I know!
