Ultimately, what irks me about this is holding on to cultural traditions that don't serve us. Tip-toeing around anatomy for the sake of Puritanical comfort breeds attitudes that make women ashamed of their own bodies and lead some people to think that when not being used for sex, vaginas are icky.
This reminds of (of course!) that wonderful female driven show, Sex and the City. In one episode Charlotte is so uptight she has never actually looked at her own vag. Its not until her mid- 30's that she finally grabs a hand-held mirror and takes a peek. What does she learn? It actually looks really nice! Also reminds of an episode where Samantha gets scrutinized by a guy for being "between waxes". She grabs a pair of clippers and turns the tables on him. He learns: Hey! It looks bigger!
While I am not suggesting we put overtly sexual material out in the general public sphere. I am saying calling a penis a "wee-wee" or a vagina a "who-ha" creates internal conflict about body image and negatively affects sexual interactions in the future, which then negatively impacts families. Whether you're a conservative Mormon or gay marriage activist, don't we all want stronger families?
So let's be honest with ourselves and each other and maybe we can help erode inferiority complexes and unrealistic expectations. And maybe advertisers won't sell products like nervous middle-schoolers.
(Current TV's Target Women is one my favorite things out there.)
