Would You Let Your 13 Year Old Watch Rocky Horror?

Was given some tickets to a RHPS screening. I think there may also be a live component, as well, but I'm not positive. I remember going several times and having fun, but that was probably 20 years ago. Obviously there are sexual themes in the movie, but I can't remember how strong they were (and obviously the tone is pretty lighthearted). I keep thinking about all the things that were a big deal back in the day but are now considered quaint by contemporary notions.

I'm really just looking for additional input/perspective. I'll probably rewatch the movie sometime this week, but what are your initial thoughts?
