Quite a bit of sexual content. One episode has the Protagonist contemplating whether or not to have sex with a woman.

One character has a bunch of plastic breasts he likes to grope, though it is played comically and not shown all that often.

There's a character called "Johnny", which represents the main character's sexual desires.

Nothing notable.

damn, hell, bastard, ass, shit

Some alcohol including characters getting drunk.

Nothing scary is in this series, at all.
