Seeing life in pink is often a metaphor. For this 31-year-old man, it is a neurological reality. With each orgasm, the world around him is briefly tinged with pinkish shades, brighter and more contrasting. This rare phenomenon, described by Iranian doctors, relates to a still little-studied form of sexual synesthesia, a fascinating condition at the borders of perception, consciousness and pleasure.
The facts: an orgasm that colors the world
The case was reported in the scientific journal Iranian Journal of Psychiatry. Doctors from Mashhad, in the north-east of Iran, describe the treatment of a man nicknamed “MR”, who came to consult for unusual sensory experiences systematically occurring after sexual intercourse.
With each orgasm, it’s quite simple, his vision changed radically:
- The colors became more intense;
- The more marked contrasts;
- And a dominant pink invaded his entire visual field.
Intrigued, the doctors conducted extensive neurological and ophthalmological examinations. Verdict: no abnormality, no visual or cerebral disorder likely to explain these symptoms. The phenomenon was neither pathological nor dangerous.
According to clinicians, it was synesthesia triggered by orgasm, a diagnosis relayed by the National Library of Medicine.
Synesthesia: when the senses mix
Synesthesia is a non-pathological neurological phenomenon in which several senses are intertwined. From Greek syn (“with”) and aesthesia (“sensation”), it designates an additional perception which is added to normal perception.
So, some people:
- See colors when reading letters or numbers;
- Associate sounds with shapes or colors;
- Perceive time in the form of spirals or landscapes;
- Feel tastes or textures in response to words.
And that wouldn’t be that rare. It is estimated that 4% of the world population is synesthete, but the figures vary greatly depending on the criteria used. What is certain is that synesthesia is neither an illness nor a mental disorder: those affected know that their sensory associations are subjective and involuntary.
More sensitive than average?
In the case of “MR”, synesthesia was not limited to sexuality. After the diagnosis was announced, he remembered experiencing another form of synesthesia during his adolescence. Suffering from heart disease at the time, he suffered from intense chest pain… accompanied by a very specific whitish vision.
Surprising fact: this visual perception only appeared during these specific pains. And it disappeared when the seizures stopped in adulthood.
The doctors emphasize the exceptional nature of this double experience. Pain-color synesthesia is already rare in itself, but the fact that it is triggered by only one type of pain is even rarer. As for experiencing an orgasm in color, it is one of the rarest forms of synesthesia ever described.
Sexual synesthesia today: a still emerging field
Long ignored by research, sexual synesthesia is only just beginning to be documented. It is defined as a neurological condition in which sexual activity or orgasm triggers atypical perceptions: colors, shapes, patterns, vibrations, sounds or alterations of consciousness.
In 2024, a major study carried out by neuropsychology researcher Cathy Lebeau, as part of her thesis at the University of Quebec, under the direction of neuropsychologist François Richer, shed light on this phenomenon.
Sixteen people with sexual synesthesia (also presenting other forms of synesthesia) were compared to a control group. The results show that synesthetes:
- Report more alterations in consciousness during sexual intercourse;
- Present more dissociative experiences;
- And experience unusual perceptions more frequently in daily life.
The descriptions collected are as varied as they are poetic. Some speak of colors similar to “cathedral stained glass”, others to “paint projected on a canvas”. Even more surprising, a 33-year-old young woman described patterns reminiscent of zebras or reptile scales during orgasm. Enough to see his antics as a real adventure!
An area which, however, remains to be clarified
Despite these advances, many questions remain. Why do some people develop sexual synesthesia and others not? What is the exact role of the limbic system? Is there a genetic origin? Why do these perceptions only occur in certain states of consciousness?
Researchers suspect simultaneous activation of several normally distinct brain regions, but the precise mechanisms remain unknown. Brain imaging techniques are only just beginning to shed light on this extraordinary sensory capacity.
One thing is certain: sexual synesthesia is neither a psychiatric disorder nor a dysfunction. In “MR’s” case, it had no negative impact on his health or sex life. He does not suffer from any erectile dysfunction and says he is perfectly satisfied. And then finally, seeing life in rosy terms, or in light during a state of grace, is it really that serious?
