Too bad about the obnoxious guys, Lee. Didn't somebody ask them to leave? I'd think that by about the second outburst it'd be time to call security.
The vulva/vagina thing was covered in the intro monologue: basically, although not technically covering the whole region, it's the best word that doesn't carry a lot of extra baggage along with it. It seems like a reasonable compromise---it's a word everybody knows, is nearly accurate, and doesn't have specific connotations.
And, of course I'm not going to argue that any female-specific thing is or is not uncomfortable; I'm obviously a little underqualified for that. What most amazed me about all of it was how much of it was stuff I hadn't really thought about much before, despite considering myself relatively well-informed. Good to have the counterpoint on the record here, though.
