When it comes to sex, many of us keep our inner worlds a secret. But here’s the truth: sexual fantasies are incredibly common. In fact, to be a sexual person is to have fantasies—it’s part of how the brain creates arousal, novelty, and excitement.
What is a sexual fantasy?
A sexual fantasy is simply an imagined scenario that turns you on in your mind’s eye. You may never act on it in real life, but just the thought can add a sense of mystery or danger that feels exciting. Think of it like mental seasoning: you might not cook that dish in your real life, but imagining it makes things more flavorful.
Why are fantasies so hard to talk about?
The very things that make fantasies thrilling—that they feel “naughty,” off-limits, or unusual—are also what bring up shame. Many people fear judgment from partners, friends, or even themselves, so fantasies often stay locked away.
Are fantasies normal?
Yes. Almost everyone has them. In fact, research suggests most people carry multiple recurring sexual fantasies throughout their lives. You’re not unusual if you fantasize—you’re unusual if you don’t.
Common fantasies you may not realize are so widespread
-
Group sex or threesomes: fueled by curiosity, novelty, and variety.
-
Public or semi-public sex: the thrill of being “caught” kicks the brain’s excitement system into high gear.
-
Being with someone older (or younger, within legal limits): power dynamics and the allure of “forbidden fruit” often drive this one.
-
Dominance and submission: for many, it’s about intensity, not pain—giving up or taking control can feel liberating.
-
Religious or taboo themes: our brains naturally gravitate toward what feels off-limits, which can amplify arousal.
What if my fantasy isn’t doable?
Don’t judge yourself. Fantasies aren’t moral statements—they’re more like mental “hot sauce.” They can spice things up in your imagination, even if you never act on them. But if a fantasy starts interfering with your ability to enjoy real-life intimacy or causes distress, it may help to talk with a therapist. Clinically, fantasies only cross into a diagnosable disorder when they cause significant distress or impairment (what the DSM-5 calls a paraphilic disorder).
Quick Quiz: Are Your Sexual Fantasies Becoming Unhealthy?
Check in with yourself by asking:
-
Do my fantasies ever cause me distress, shame, or interfere with my ability to enjoy real-life intimacy?
-
Do I feel like I need these fantasies to get aroused, and struggle without them?
-
Do my fantasies take up so much mental space or time that they pull me away from other parts of my life?
-
Have I ever acted on a fantasy in ways that caused harm to myself or others?
If you answered “yes” to one or more of these, it may be worth exploring with a therapist. Fantasies can be fun and healthy—but if they start running the show, support can help you regain balance.
How to safely explore fantasies
-
Communicate with your partner(s): Consent and honesty are key.
-
Experiment gradually: erotica, audio, or role-play can help bring a fantasy into reality without going all in.
-
Keep balance in mind: Fantasies should enhance, not replace, real-life connection.
