Easy, straightforward question about Jennifer's Body? (NO SPOILERS, I PROMISE)?

Are there any inappropriate scenes and is it used excessively? I'm not a perv, lol. It's just that I'm seeing it with a parent and it would be extremely awkward, lol. We have seen films that do contain nudity/obligatory and it was no problem, like Watchmen. Is there a lot? 2 to 3 scenes is okay, but more than that is an issue!
