it is a classic funny movie, very interesting subject, really interesting stuff to talk about with kids: after all is it nature or nurture?
but really, breasts everywhere. Jamie Lee`s breasts twice, other women in minor roles, parties with naked people dancing.
People smoke joints , there is cocaine in one scene. Swearing too.
Having said that, no serious violence, no actual sex, lots of sex suggested though.
I wouldn`t go as far as 17 but 13 maybe...
