Since I am both far too old to follow Katy Perry on Twitter and too completely uninterested in celebrities’ personal lives to read The Huffington Post (WTF? Didn’t HP used to be a political blog?), a friend had to tip me off to the big news that Katy Perry is menstruating and presumably not pregnant.

The image at right is of one of Ms. Perry’s Twitter messages from Wednesday, which reads, “ur gonna make me cry, maybe that’s my period tho. THAT’S RIGHT I’M BLEEDING. Face. Better luck next month peepz”.

As far as I’m concerned, Katy Perry can tweet about her period until the cows come home – hell, that’s what Twitter is for. And in general, the more open acknowledgment that Menstruation Exists, the better for all menstruators. But the comments on the Huffington Post article provide another fascinating study in communication about menstruation. I don’t have enough Sanity Watchers points to read all six pages (and still accumulating) of comments, but I did scan a couple of pages. Most of the comments are along the lines of “TMI” and “It’s gross to discuss that kind of stuff.” One Perry fan posted this remark:  “Katy, get pregnant fast so that you can talk about that instead of this.”

Apparently it’s acceptable to talk about the contents of one’s uterus only when it’s full.
