When people run up against a turn-on that embarrasses them, the first instinct is usually to crush it. That doesn't work. Desire is like a ball held under water — the harder you press it down, the harder it springs back. Press long enough and what you get is despair, then drift, and finally the loss of any sense that you're steering your own life. The way through a kink isn't war with yourself. It's growth.
So before you decide whether yours is "normal," it's worth getting the test right — because the one most people reach for is the wrong one.
People love to say every kink is harmless, no kink is wrong. It's a comforting line, and it's only half true. Picture a man who gets off on spying on women in a public restroom — peeping at strangers who never agreed to be looked at. Read that and the slogan falls apart in your hands. There's a victim in the frame. So the real question isn't whether your preference is rare. It's something else entirely — and it's worth walking through how the experts got there.
What does "sexual preference" actually mean?
Sexual preference — what some people call a kink or a fetish — is just what a person is oriented toward, sexually: the object and the act. Put plainly, whatever switches the arousal on is that person's preference.
Most people are drawn to the opposite sex; probably around 90% of the world works that way. But the preference runs the other direction for plenty of people too — toward the same sex, or toward something that isn't a person at all: high heels, stockings, lingerie.
From a biological angle, this is exactly what you'd expect. To keep a population resilient, almost every species varies — it doesn't cast every member from a single mold. Variation is what lets a population explore in every direction at once. So different people end up with different temperaments, different faces, different sexual preferences. That's not a malfunction. That's the design working.
But humans are social animals. The moment people live together in groups, preference stops being private and picks up a political charge — it gets ranked, sorted into better and worse, right and wrong.
How did unusual desires get labeled a sickness?
In 1913 the sexologist Friedrich Salomon Krauss helped popularize the word paraphilia — an attempt at a non-pejorative term for atypical sexual interest. It didn't stay neutral for long. The word was quickly politicized into a tool for intimidating gay people and branding them as diseased: See? This is an illness. You're not normal. Round them up, lock them in the asylum. Because of that smear, by the middle of the 20th century, "paraphilia" had become, in practice, a label for homosexuals and anyone who wasn't straight.
Humanity's road to understanding its own desires has been a crooked one. Before the 1980s, the entire standard for sorting "good" preference from "bad" was a headcount. Line up with the majority and you were healthy. Diverge and you were sick — go get treated.
A few cases from that era:
In 1983, a 29-year-old man in Florida was discovered by his mother to be secretly wearing women's clothing and masturbating while cross-dressed. She brought him to a psychiatrist, where he was diagnosed with a sexual deviation; after several months on Selegiline, the "symptoms" eased.
In 1991, a 52-year-old man in Los Angeles was found by his wife to have repeatedly bought young women's underwear. She went with him to a psychiatrist. After a year on Selegiline he was put on pramipexole 1.5 mg three times a day, and his fetishistic leanings reportedly diminished.
Both cases show the same thing: in those years, a preference that didn't match the majority was routinely read as a disease and treated as one.
When did doctors stop treating "different" as "sick"?
In the late 1980s, a clear split opened up among the clinicians doing this work. Years of treating patients had taught a lot of frontline doctors something the model didn't predict: you cannot turn a person's sexual preference around with drugs. Medication can temporarily lower desire — blunt the libido of whoever's taking it — but it doesn't reverse the preference itself.
Which means: if the goal is to keep that desire suppressed, the person has to stay on the drugs long-term, maybe for life. And the side effects are not subtle — osteoporosis, depression, Parkinsonism, and other documented after-effects are on the record.
So people started asking the obvious question. Just because a preference differs from the majority's, should someone really be diagnosed as "deviant," then medicated indefinitely? Is that good medicine?
In 2006, the psychiatrist Charles Allen Moser published a paper in the Journal of Psychology & Human Sexuality making the point bluntly: if you treat one of a person's states of mind as a mental illness, you stigmatize a whole category of people. On that basis, the field began splitting "paraphilia" into two kinds — those with a victim, and those without.
The ones without a victim are simply paraphilias, and they need no psychiatric treatment at all.
What's the difference between a paraphilia and a disorder?
Take a man with a cross-dressing kink who likes wearing women's clothes and heels. If he wears them at home after work, or during sex, and his partner understands, then he's harmed no one and disrupted nothing in his social role. The next day he takes the clothes off and goes back to a normal life and a normal job. Medically, he isn't sick.
Or take BDSM between adults: if the activity happens with both parties' consent and causes no uncontrollable accidental injury or lasting harm to the people involved, it shouldn't be read as an illness either. (If you play at the heavier end, the part most people skip is the aftercare — and that's the part that keeps it healthy.)
The other category is the one that matters. The ones with a victim are called paraphilic disorders — genuine mental illness, and they do need treatment.
Same fetish, two outcomes: A likes to smell his own partner's underwear. B likes to steal a neighbor's underwear to smell. The difference is obvious — B's behavior produced a victim. That preference is harmful.
BDSM splits the same way. I once knew a man — he was in Canada — who came to me distressed. Every time he played with a partner, he couldn't stop himself from ignoring her safe word; he'd only stop once he'd gotten off. "Once I'm in that state," he said, "I can't pull out of it for anything. My partner is terrified, and afterward I'm sick with regret." I told him to see a doctor immediately. He was ultimately diagnosed with a mild personality disorder — the kind that has to be treated. (A safe word is not optional; the moment it gets overridden, it isn't a scene anymore, it's harm. The same trust is what the whole keyholder dynamic rests on.)
And then there's pedophilia, which isn't only an illness in medical terms — it's a crime, with a victim built in. The same goes for the voyeurism we opened with. Both produce a clear victim, and both are classified as paraphilic disorders.
Can the victim be yourself?
There's a special case inside "paraphilic disorder": the victim is the person himself — he perceives that one of his own preferences has begun to wreck his ordinary life, and he needs help.
Psychology Today ran a case like this. In 2006, a mortuary worker in Pennsylvania sought counseling, reporting a severe exhibitionism: any time he saw a member of the opposite sex walking alone, he had the urge to open his pants and expose himself. Reason kept him from actually doing it — but the urge tormented him, to the point that it bled into his daily work and his social life, leaving him anxious, depressed, and unable to be friends with women. In that situation the doctor still issued a paraphilic-disorder diagnosis and began treatment.
In other words: the current clinical consensus for sorting these conditions is no longer about majority versus minority. It's this — no matter what your preference is, however strange, as long as it causes no suffering to anyone else, or to you, that can't be resolved without medication, it isn't diagnosed as an illness. If it does, it is.
The DSM-5, released in 2013, drew the line explicitly: it separated paraphilia from paraphilic disorder and stated that a paraphilia on its own needs no treatment.
Take sadistic interest. To decide whether it's a disorder, the actual criteria read like this:
Sexual Sadism Disorder, 302.84 (F65.52). Both must be met:
- Over a period of at least 6 months, recurrent and intense sexual arousal from the physical or psychological suffering of another person, manifested by fantasies, urges, or behaviors.
- The individual has acted on these urges with a non-consenting person, or the urges or fantasies cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
Where do these preferences even come from?
Someone always asks: how do all these wildly varied preferences form in the first place? Honest answer — medicine and psychology still haven't worked out the mechanism.
Some researchers think it's innate. In 2008, Dr. Rahman published a paper in Archives of Sexual Behavior arguing that a higher 2D:4D digit ratio — the index finger being notably longer than the ring finger — tracks with higher prenatal estrogen exposure, and with a higher probability of developing a paraphilia.
Others think the real nature of it is a teenage pattern of satisfying desire. Take a foot fetish — most people can't fathom why anyone would be drawn to a stranger's feet. Picture it like this. A 13-year-old boy crosses paths with a stylish, sexy grown woman. The hormones hit; he's all impulse — and at the same time crushed by his own inadequacy, because he's a boy, with no real means of pursuing the woman in front of him, not even the nerve to walk up and ask for her number. So what does he do? He drops his head in embarrassment — and finds himself looking at her feet.
Now the follow-up: when he thinks back on her afterward, what surfaces in his mind? Her face, her smile, what she was wearing? No — between the shame and the panic he barely looked, just registered "pretty." What he comes back to is her feet, because that's the part he looked at the most. A few more times, the habit sets, and the fetish is formed.
We still haven't nailed down the exact cause — but who cares? Suppose one day humanity figures it out, and even engineers a fix: a technology that could correct every human's preference to be perfectly identical — all heterosexual, all marrying and having kids on schedule. I'm certain that would be the single worst technology in the history of science. It would strip the species of its diversity, kill off countless strange directions of evolution and imagination, and leave us less able to withstand risk in a natural world that runs on selection.
So how should you regard an unusual kink?
The whole point of all this: you don't judge right from wrong by whether something is rare or common. You judge it by whether it causes suffering and harm.
For the kinks that hurt no one, the right move is generosity — give them respect. Humans have the right to decide how to use their own bodies in pursuit of their own particular satisfaction. Branding a preference "deviant" just because it differs from the average makes no real sense.
But for the kinks that produce a victim, you also can't dress them up with a slogan like "no kink is wrong." The instant one violates someone else's rights, it's something a society should reject and punish.
So hold yourself to that standard. What are your kinks — and is there a victim? That's the only test worth running.

Different isn't the same as wrong, and consensual isn't the same as harmless until you've actually checked. If your scene runs to the heavier end, the gear should match — clear, body-aware, and built for play that two people agreed to. See the BDSM gear collection.
