Do you know the child well enough? I saw GYPSY for the first time when I was 6 (the movie) and I've loved it ever since. It totally depends on the child and his/her interests, attention span, and maturity level.
And as for the subject matter, I would say that the child is exposed to far worse than strippers on a daily basis everywhere he/she goes. If the child has questions after, answer them - avoiding the show to avoid the inevitable questions is lazy parenting, in my opinion.
Cheyenne Jackson tickled me. AFTER ordering SoMMS a drink but NOT tickling him, and hanging out with Girly in his dressing room (where he DIDN'T tickle her) but BEFORE we got married. To others. And then he tweeted Boobs. He also tweeted he's good friends with some chick on "The Voice" who just happens to be good friends with Tink's ex. And I'm still married. Oh, and this just in: "Pettiness, spite, malice ....Such ugly emotions... So sad." - After Eight, talking about MEEEEEEEE!!! I'm so honored! :-)
