Casual sex does not appear to cause depression. Deutsch 2015 examined 714 twins across 357 twin pairs and found no causal relationship between casual sex in adolescence and later depressive symptoms or suicidal ideation. Fielder 2010 reported that penetrative-sex hookups raised psychological distress among 109 female first-semester students but not among 31 male students. Townsend 2020 linked non-autonomous motives to lower self-esteem in 284 college students. Canivet 2022 grouped 566 adults into 4 fantasy profiles. Brotto 2021 found that attention training reduced sexual distress more than supportive sex education, while Adam 2020 found both programmes reduced distress.
The evidence is uneven. The casual-sex studies are mostly North American college samples, correlational or short-term, and the twin study and the short-term college study point in different directions. The fantasy study surveyed reactions to 4 written scenarios online and did not test escapism. The programme trials enrolled women with a diagnosed difficulty, not healthy couples. This text reports what those samples measured and claims nothing beyond them.
Does casual sex itself lead to depression and psychological distress?
The twin study and the short-term college study diverge. Deutsch 2015 found no causal relationship between casual sex in adolescence and later depressive symptoms or suicidal ideation in 714 twins, in either direction. Fielder 2010 found that penetrative-sex hookups increased psychological distress among 109 female first-semester students but not among 31 male students.

The discordant-twin design compares twins within the same family, so shared background is held constant, and it follows outcomes into young adulthood. Fielder 2010 followed 140 first-semester college students briefly and measured distress close in time to reported hookups. Different samples, time frames and measures mean the results cannot be merged into a single verdict.
Does the motive for casual sex shape its psychological outcome?
Motives shape the pattern in the data available. Townsend 2020 studied 284 American college students and found that non-autonomous motives for casual sex were linked with lower self-esteem in both sexes and, in women, with more depression and more sexual victimization, compared with autonomous motives. Autonomous motives were more strongly associated with casual sexual behavior in both sexes.
Autonomous motives mean the person chooses the encounter for reasons that are their own, such as fun and enjoyment. Non-autonomous motives mean the person is mainly responding to something external, such as wanting to please someone else. Townsend 2020 found that autonomous motives were positively associated with sexual victimization in women but not in men. These are correlations between motives for casual sex and psychological outcomes in 284 American college students.
What do sexual fantasies tell us, and can they be called an escape from reality?
Canivet 2022 surveyed 566 adults from Canada and the United States about arousal and discomfort toward 4 fantasy scenarios and identified 4 classes: Indifferent 37 percent, Romantic 22 percent, Enthusiastic 26 percent and Dissonant 15 percent. No retrieved article tested whether fantasy works as an escape from stress.
The classes differed by gender, childhood sexual abuse experience, sexual compulsion and romantic attachment, and the authors suggest that the relationship with fantasies may reflect the overall relationship with sexuality. Because no retrieved article measured fantasy as a way of escaping stress, the escapism label remains a hypothesis rather than a finding, based on 566 adults from Canada and the United States.
Is there research evidence for playing down orgasm and attending mindfully to the body?
Yes, in women with a diagnosed sexual difficulty. Brotto 2021 randomized 148 women with low desire or arousal to an eight-session group programme that trains non-judgmental attention to bodily sensations or to a group programme of supportive sex education, and both groups improved.
Desire and arousal improved with large effect sizes, d from -1.29 to -1.60, similarly in both groups, while sexual distress and rumination about sex improved more after attention training, d from 0.83 to 1.17 and d from 0.42 to 0.69. About half of participants reported moderate or great improvement, and gains held at 12 months.
Brotto 2024 reported that perceived stress fell in both groups, more after attention training, and that this reduction predicted increased desire and decreased sex-related distress after attention training only. Adam 2020 studied 65 women who had difficulty reaching orgasm, 35 in a video-based self-guided attention version and 30 in a video-based cognitive-behavioural version; both groups improved in functioning, distress, desire, arousal, orgasm and satisfaction, while pain fell only in the cognitive-behavioural group.
These trials enrolled women with a diagnosed difficulty, low desire or trouble reaching orgasm, not healthy couples. A PubMed search for the word Karezza returned 0 records on 2 October 2026, so the claims made for it online are untested.
In clinical sex therapy, specialists often see that the pressure to reach orgasm becomes a source of anxiety in itself, and that turning attention back to the bodily sensation of the moment eases that tension.
[More research needed: none of the articles retrieved for this text directly tested Karezza or erotic escapism as such.]
The editorial position of the Behckam.com site is that casual sex or fantasy is neither inherently healthy nor unhealthy; what matters in the research is motive, freely given consent and the outcome a person actually experiences.
The evidence is mixed. Deutsch 2015 found no causal relationship between casual sex in adolescence and depressive symptoms or suicidal ideation among 714 twins. Fielder 2010 found that penetrative-sex hookups increased psychological distress among 109 female first-semester students but not 31 male students.
How much do motives matter in casual sex?
Motives are associated with different outcomes. Townsend 2020 found that among 284 American college students, non-autonomous motives were linked with lower self-esteem in both sexes and, in women, with more depression and more sexual victimization than autonomous motives. The links are correlational rather than causal.
Is having sexual fantasies a sign of a problem?
Fantasy content varies widely rather than signalling disorder. Canivet 2022 classified 566 adults from Canada and the United States into 4 groups, including 15 percent Dissonant, who reported high arousal and high discomfort. No article retrieved here tested escapism, and distress or impairment in daily life is a reason to consult a professional.
Is sex without a focus on orgasm backed by scientific evidence?
Partly. Brotto 2021 found that 148 women with low desire or arousal improved in desire and arousal with large effect sizes, d from -1.29 to -1.60, and distress improved more with attention training; Adam 2020 found 65 women with orgasm difficulty improved in both programmes. These trials tested clinical samples, and Karezza remains untested.
What research concludes about casual sex, fantasy and sex without a goal
The picture is not bleak. Across 714 twins in 357 twin pairs, casual sex in adolescence showed no causal relationship with later depressive symptoms or suicidal ideation, while the 140 first-semester students and the 566 adults surveyed on fantasy show that context and reaction matter. In the trials, 148 women with low desire and 65 women with orgasm difficulty improved. Motive, consent and the outcome a person actually experiences remain the variables that future research can measure.
