Monsterfucker
A monsterfucker is someone who is sexually or romantically attracted to fictional monsters, creatures, or other nonhuman beings. They may explore this interest through fantasy, hentai, erotica, artwork, games, costumes, or roleplay.
The monsters involved are usually imagined as intelligent beings capable of consent, rather than real animals. They may be supernatural, alien, monstrous, or simply very different from humans.
Origins of the Term
The exact origin of the term monsterfucker is unclear. One of its earliest known appearances is in the 2008 science-fiction novel "Marseguro," although the word may have circulated informally before then. It later became a humorous and sometimes proud self-description within online fandom, particularly on Tumblr.
The term’s growing popularity also appears closely connected to the rise of monster romance. Paranormal erotic romance had already built an audience around vampires, werewolves, demons, shapeshifters, and other supernatural beings by the late 2000s. In the early 2020s, BookTok helped bring more overtly nonhuman romance, including alien and monster love interests, to a wider readership. These books expanded beyond mostly human-looking creatures to include aliens, orcs, minotaurs, dragons, tentacled beings, and other distinctly nonhuman beings.
Google Search data suggests that searches for monsterfucker also began rising significantly around 2020, indicating that the term was moving beyond smaller fandom communities at roughly the same time.
Why People Are Into It
People fantasize about monsterfucking for many reasons. Here are a few common ones:
Nonhuman Bodies
Monsters can offer bodies humans simply can’t: tentacles, tails, claws, fangs, multiple limbs, impossible proportions, and unfamiliar anatomy. Some people love fantasizing about the ways those features could touch, restrain, penetrate, or overwhelm them.
Impossible Fantasies
Monster fantasies make room for experiences that couldn't happen in real life, like magical transformations, shapeshifting, or supernatural possession.
Size and Strength Differences
Some people enjoy imagining a monster that is much larger, stronger, or more powerful than they are. This may overlap with dominance, submission, bondage, restraint, or being physically overwhelmed.
Fear and Danger
Fear can be a potent sexual catalyst for some people. They may love imagining a monster who is much larger, stronger, and more powerful than they are (and being a little afraid of it!) This may also overlap with dominance, submission, bondage, restraint, or the desire to be physically overwhelmed.
Freedom From Human Expectations
A fictional creature does not need to follow ordinary ideas about gender, bodies, beauty, sex, or relationships. For some people, this makes monster fantasies feel more accepting and less judgmental than fantasies involving humans.
Identifying with the Monster
Some people don't only desire the monster, they relate to it. Monsters often represent people who feel different, excluded, misunderstood, queer, disabled, or otherwise outside the norm. Monster romance can turn that difference into something desirable and powerful rather than shameful.
Transformation or Corruption
Vampires, werewolves, demons, parasites, and undead creatures can offer fantasies about being bitten, infected, changed, possessed, or made into something nonhuman. The appeal may be losing control, becoming more powerful, joining the monster, or leaving one’s former identity behind.
Not every monsterfucker is interested in all of these things. One person may like mostly human-looking vampires or elves, while another prefers creatures that look and behave very little like humans.
