Is there anything more phallic than Cupid's bow? Any holiday symbol that looks more like a woman's tush when she's bent over? I don't know about you, but I think Valentine's Day is all about the sex.
I had a little snicker just now, too, when I looked up the history of Valentine's Day in that most dependable source of information, Wikipedia (not!). The article says that Valentine's Day came to be during Chaucer's times of "courtly love."
Well, having started my education with a B.A. in English, I can tell you that Chaucer is bawdy, and not "courtly" at all! Chaucer was all about the sex. I guess that's why, back in the day, we weren't given Chaucer to read until college.
So if your partner brings you champagne and roses, or a card and chocolates, or a bottle of lubricant and a toy, and then wants sex, for goodness' sake, don't be insulted.
Let good old Cupid pierce you, right in the…heart.
