A very short kissing scene between a boy and a girl that only lasts a few seconds.

some boys talking about each others' genitalia while they were in the bathroom (some reference to pubic hair)

A guy says something like "nothing like the feel of a woman's breast.... in your mouth".

It's explained and partially shown that a character was stabbed. Blood flows into a swimming pool and the fresh wound is shown.

About 5 minutes in a teen boy jumps from roughly 10 foot onto a patio and breaks his ankle. We see his foot snap 90 degrees accompanied by a crunching sound. No blood or gore but will make you whince.

Men are seen smoking cigarettes and cigars.
