What do you know about women's orgasms? If you're a woman you know about your own ones but you're probably in the dark about whether they're the same in quality and quantity as your friends' (they're probably not) and if you're a man, unless you're particularly attentive, the whole thing is most likely a total mystery.
My least favourite euphemism in the English language is, "down there", in reference to the female sex-organ-and-peeing-area. As in, "my pants are making me itch *down there*", or "before the c-section, you'll have to shave *down there*". Like we're still calling it "down there" when I'm about to have my uterus opened up.
