Invented Sex: Too Racey or Harmless Fun?

For those of you who aren't familiar with the song or video by Trey Songz "Invented Sex", I posted it on my page so that you can be a part of this discussion as well.
Obvious by its title, the video is about sex. But is it considered 'too much' for the general public, or access by way of internet to those who may be considered underaged or too young?
As soon as the video was released, all of my girlfriends rushed to the official 106 & Park website to view it, or more specifically, him. The him I'm refering to is Trey Songz, who has been dubbed "sexy" in my network of girlfriends. Although I may agree with them, and appreciated the video, I wonder if its a little over the top for our younger viewers.
Do you think that its just harmless fun for those of us old enough to appreciate the art for what it is? Or do you think that it's too racey for our younger crowd and should therefore have perimeters on where its played? Or is it strictly the responsibility of the parent to monitor what their child watches?
