Basic Trope: Aliens have the same genitals as humans.
- Straight: Burthe, a Rubber-Forehead Alien has a penis like a human male does.
- Exaggerated: Not only do Human Aliens and Rubber-Forehead Aliens have human shaped genitals, but so do Humanoid Aliens, Starfish Aliens, and even Energy Beings.
- Downplayed: Exotic Equipment.
- Justified:
- The aliens are shape-shifters who can change their form into that of a human's.
- Panspermia is part of the background to this work's universe; all races are genetically similar as they were deliberately engineered to be by the Precursors.
- Inverted: Bob, a human, inexplicably has bizarre and alien genitals.
- Subverted:
- Just as Alice is about to get down and dirty with Burthe, she discovers that he has different genitals from a human's.
- Despite the resemblance of indeed 'usability' for Alice's pleasure Burthe's 'equipment' is another exotic organ and about as likely to get him off as rubbing a human's nose. His actual genitals are under his tongue.
- Double Subverted: Only for her to find out that it was just part of a bodysuit.
- Parodied: Absolutely every lifeform in the universe has human shaped and sized genitals making insects look like ambulatory genitals.
- Zig Zagged: Some aliens have human-like genitalia, others do not.
- Averted:
- The aliens have different genitals from humans'.
- The aliens have no genitals at all.
- Enforced: Burthe could not be Mr. Fanservice without human genitalia.
- Lampshaded: “I’d complain about how unlikely it is that we have compatible genitals if not for the fact that we can have sex!”
- Invoked: Burthe uses Voluntary Shapeshifting to give himself human gentialia.
- Exploited: Since it’s so easy to have sex with aliens, spies can use Honey Traps against them to gain various advantages.
- Defied: All aliens in the setting use Bio-Augmentation to ensure that no two species have similar genitalia.
- Discussed: "Didn't you notice how many aliens have human genitals?"
- Conversed: ???
- Implied: Burthe is known to have a successful sex life with many human beings.
