Most episodes have many sexual references, including masturbation, threesomes, swinging, bi-sexuality, homosexuality, anal sex, and a continuous ongoing joke about bestiality with an ostrich.
The hockey team consistently talk about having sex with women on their out of town schedule, including slang terms about sexual organs.
The horny female bar owner is always making sexual remarks and advances at anyone and everyone, while girating.
Katy occasionally wears a bikini around the farm. Most of the time, she wears a white bottom piece that (from certain angles) can appear to show what's underneath
It's implied (in some episodes) that Katy is bisexual. In most episodes, she is attracted to guys. But there are some episodes where she either finds a girl attractive or that she and a girl went off together for a certain purpose.
The 8th season has an episode in a Strip Club with partial female buttocks nudity via thongs, partial breast nudity with X's as partial nipple coverage & women scantily clad.

It is occasionally mentioned that a minor character (allegedly) had sex with an ostrich, and the main cast discuss the logistics of how this could be accomplished, particularly if one would need acomplices or if maybe the ostrich was sick.
At the beginning of Season 11, Reilly and Jonesy find Ron and Dax (the gay series regulars) in the gym. Ron and Dax mention they're trying to look like gay porn stars. Glen then comes into the conversation. Glen pulls out his fitness inspiration, which is a gay porn magazine. No real nudity is seen, but several pictures are shown from the magazine which depict sexual acts. There are several other scenes in which Reilly and Jonesy talk to Glen about being gay.
The McMurrays are implied to be a swinger couple and overly sexual. Throughout the series, there are numerous implications of who they've been with, as well as numerous innuendos. However, they are drunk in many of the scenes which just adds to the comedic effect.
