I assume that hereIam, like most people, doesn't make a habit of checking the genitalia of people they meet (except, perhaps, any sexual partners). I know I don't usually start off my conversations with strangers with "so you DO have a vagina then?", or variations thereof...

Ah, well, Sparkly, I'm sure you'll get used to it.
