Fetish 101: Aliens

Fetishes are a normal part of being a sexual human. What turns you on is individual and unique. HUD App’s “Fetish 101” series aims to destigamitize, educate, and clarify, so we can all learn and feel good about our desires.

Alien fetish – or exophilia, if you want to impress someone at a party – is an attraction to beings who are literally out of this world. Sometimes it’s about actual little green men, sometimes it’s about blue-skinned babes from sci-fi movies, or just the fantasy of exploring new frontiers in the bedroom.

Pop culture has given us everything from “sexy Starfleet” to “tentacle romance novels” (don’t Google that at work). Social media has only turned up the dial: TikTok is full of “alien boyfriend/girlfriend” edits, and conventions like Comic-Con are ground zero for human/alien flirting.

So why are aliens a turn-on?

There’s a lot going on in the brain when it comes to close encounters of the third kind. Part of it is the classic thrill of the unknown – aliens represent mystery, adventure, and the idea of “anything goes.” There’s also the fantasy of being desired (or abducted) by someone who doesn’t follow human rules, and who might see you as fascinating, rare, or even precious.

Alien fantasies let is play with difference, with power, with being seen as special and unique – or with seeing someone (or some-THING) else as special and unique. Literally out-of-this-world. Plus, there’s something freeing about imagining intimacy with someone who doesn’t care about boring Earth stuff like bad hair days or awkward small talk.

It’s not always about little green men

Exophilia covers a spectrum. For some, it’s about roleplay – think metallic body paint, light-up toys, or speaking in “space languages” you make up on the fly. For others, it might be inspired by sci-fi media (hello, cosplay) or just the feeling of being with someone totally outside your usual (human) type.

The tentacle subgenre and ovipositors are their own thing; blame anime, internet fanfic, and a lot of creative imaginations for that (and we’re here for it, frankly). The common thread: It’s all about curiosity, escapism, and sometimes, a dash of the forbidden.

Consent is still universal

No matter how out-there your fantasy, consent and communication are non-negotiable. Before you bust out the silver body paint or try to “beam someone up,” talk about boundaries, what feels good, and what’s a hard no. Alien roleplay can bring up themes of power, submission, or being “taken into your flying saucer” – but even these need check-ins and aftercare. If it’s not fun, safe, and agreed-upon, it’s not sexy.

Tips for an out-of-this-world encounter

• Start small: Want to test the waters? Try alien-themed lingerie, glowing accessories, or a “cosmic playlist” to set the mood.
• Roleplay it up: Come up with silly/steamy alien names, invent rituals, or pretend you need to “learn human customs” (Bonus: You can ask for a kiss every time you don’t understand Earth slang).
• Keep it safe: If you’re trying sensory play, costume makeup, or toys, check for allergies, wash everything thoroughly, and never use body paint where the sun doesn’t shine.
• Debrief after: Share what you liked, what was weird, and whether you want a sequel. Even aliens appreciate good feedback.

What if you’re not into it?

Totally normal. Exophilia isn’t for everyone. Maybe you’d rather keep your bedroom strictly terrestrial, or just enjoy the memes. You do you. Alien kinks are just another flavor in the vast, intriguing universe of human desire. As long as everyone is informed, enthusiastic, and into it (even if you are pretending to be full-body probed), you’re all cleared for liftoff. Beam us up, and don’t forget to pack the lube (because as far as we know, nobody has discovered that on a distant planet yet…).
