Yes, I agree with just about all the comments here. Those kinds of things are personal, and ought to be kept private.
When we were kids, we watched "the film" at school. They kept all the girls after school, and sent the boys home (but they tried to hang around and peek in the auditorium windows). It was a bit embarrassing to have it handled that way (well, actually it had more to do with a nosy teacher who made inappropriate remarks).
But the whole idea of that commercial ... yeah if that's on TV, I have to say that is just no class.
Do young boys want to see stuff like this?
Would young girls want to see films relating to pubescent boys' "issues"?
Do they want to be sitting in the same room when the commercials come on?
Just seems in poor taste to me. And they really HAVE such parties??? I would have been mortified. Not because I'm ashamed of it but ... it's just that it was something I kept between myself, my grandma (because it happened at her house), and my mom.
And when it came up with my daughter, I kept it between the two of us. No need to announce it to the world, imo. She would have been upset with me if I had.
