Fantasy, and what it does and does not mean

Large surveys of sexual fantasy consistently find that the great majority of adults have them, that the content is more varied than people assume, and that most people believe theirs are unusual.

What the research finds

Studies collecting fantasy content from large samples find a small number of very common themes and a long tail of individual variation.

Themes involving novelty, multiple partners, power exchange and being desired appear repeatedly across populations.

Very few reported fantasies turn out to be rare when compared against the full sample, which is the single most reassuring finding in this literature — the belief that one's own fantasies are abnormal is itself the most common feature.

Fantasy is not intention

The distinction that resolves most of the distress.

Studies asking people whether they want their fantasies to occur in reality find that a substantial proportion do not, and the gap is largest for exactly the themes that cause the most shame.

Fantasy operates without consequence, without negotiation, and with complete control over the scenario — none of which apply to reality, which is why a scenario can be arousing to imagine and unwanted in practice.

This is particularly important for fantasies involving coercion or loss of control, which are common, are found across genders, and are not a wish for the real event.

The most plausible explanations involve the removal of responsibility and the intensity of being wanted, rather than any desire for harm.

Where shame comes from

Not from the content itself, generally.

It comes from believing the fantasy reveals something true about your character, from religious or moral frameworks that treat thought as equivalent to action, and from the absence of any information about what other people experience.

Which is why the single most effective intervention for fantasy-related distress is accurate information about prevalence.

Clinically, distress about fantasy is more common and more damaging than anything the fantasy contains.

When it does warrant attention

A short and important list.

Fantasies involving children, which are not in the ordinary range and for which confidential help exists — services in several countries specifically support people distressed by such thoughts who have not acted, and using them is the responsible course.

Fantasies that are becoming compulsive, intrusive and unwanted, particularly where they resemble obsessive-compulsive intrusions rather than desires — a distinction a clinician can make and which changes the treatment entirely.

Any situation where someone is planning to act in a way that would harm another person.

And where fantasy has become the only route to arousal in a way that is causing difficulty in a relationship, which is a treatable pattern.

Sharing them

The practical question in relationships.

There is no obligation to disclose fantasies, and privacy of inner life is legitimate.

Where sharing is wanted, it works better with preparation: agreeing in advance that this is information rather than a request, starting with something less exposing, and not doing it during or immediately after sex.

The receiving partner's job is to hear rather than to react, and the most common mistake is to interpret a fantasy as a statement about the relationship's inadequacy.

Some fantasies are best kept as fantasies, and saying so is a complete answer.

Acting on them

Where couples choose to.

The things that make it go well are unglamorous: explicit prior discussion of what will and will not happen; an agreed way to stop; discussion of how each person will feel afterwards; and a conversation the following day.

Expectations frequently exceed reality, since the fantasy version has no logistics and no awkwardness.

And anything involving other people requires considerably more planning than couples usually give it, since the risks to the relationship are real and are not evenly distributed.

The absence of fantasy

Worth mentioning since it worries people too.

Some people report few or no sexual fantasies, and this is within the range of normal — including for people with entirely satisfying sexual lives.

Aphantasia, the absence of visual imagery, affects a small proportion of people and changes how fantasy works for them.

And low desire is associated with reduced fantasy, which makes it a symptom rather than a separate problem.
