Casual sex is not harmful in itself, but neglecting personal needs or emotional boundaries can have negative emotional consequences for some people. Despite the promise of freedom and easy intimacy, casual sex can leave some women feeling drained.
DW spoke to women from North America, Europe and Asia who described their experiences: sexual adventures gave them a sense of self-confidence in the short term, but later found it more difficult to achieve deeper intimacy.
Heather, a 40-year-old from the US, describes the conflict as a feeling of "emptiness, sadness and temporary power, but always with a desire for more." During casual sex, she often tried to "turn off emotions," which she experienced as "cutting off a part of myself."
Her experience of the negative side of this sexual culture coincides with a little-researched condition called postcoital dysphoria (PCD) – when people feel sad, irritable or need to cry after sex.
In a 2020 study, women reported these symptoms after consensual sex or masturbation – some said it occurred after orgasm – along with feelings of exhaustion or emotional instability for hours or days afterward.
Men also report PCD, but historical stigma surrounding women's sexual autonomy and personal expectations have led some studies to show that as many as three out of four women experience PCD after casual sex.
Motivation is different – and the results are different
"I don't think I'm cut out for the culture of casual sex," says Ishta, a French woman of Indian descent in her 30s. "I crave a relationship more than sex. I often hoped that my partner would develop feelings for me or that we would start dating."
Sexual desire is a complex phenomenon. Some research shows that women's sexual desire is often shaped by a need for closeness, which makes it difficult to maintain emotional distance during casual sex.
Tara Suvinjatichjaiporn, a professor of sexual and relationship communication at California State University, claims that this is often a consequence of how girls are raised:
"Women are socialized from a young age to be caring, warm. And those are the opposite traits of emotional distance. That's why it's much harder for them to have casual sex," she says.
Symptoms of PCD can occur when the desire for intimacy remains unfulfilled, and can be further exacerbated by low self-esteem. Although not the rule, people with higher self-esteem who engage in casual sex are often not affected by negative emotional consequences.
“But many people, both men and women, engage in it for external validation,” Suwinyatichayporn adds.
This can lead to stress around long-term relationships, especially if a meaningful connection remains elusive.
"I used to be extremely romantic, and now I feel like I'm acting in front of the men I want to sleep with," says Išta. "I don't think I trust people like I used to," says Heder, who has experienced a decline in self-confidence and a negative attitude towards potential partners - "a belief that men are unreliable, sex-obsessed and self-centered."
"In return, I sometimes felt less valuable, like I was being used," she adds.
Without feeling guilty
Recent research, mostly on North American couples, has shown that those who paid attention to their feelings during sex, without judgment or guilt, had better sexual functioning.
Suvinjatichjaiporn says that many people lack this awareness when having casual sex. By its nature, casual sex often skips the conscious connection that makes the experience emotionally stable. Casual sex can be "emotionally numbing" for both women and men.
“I explored polyamory to the fullest and pushed myself to the edge, and in the end I felt exhausted and unstable… My nervous system couldn't handle it,” says Heather.
Today, she wants real intimacy, not fleeting pleasure. But she came to this realization only after honest introspection—a process that can help women understand the experience of casual sex.
For those who feel emotionally drained, Suvinjačajporn advises taking a break from casual sex to create space to slow down and think about their feelings and needs, without external pressure.
"Because you want to be alone for a while while you work on yourself," she says.
How to restore balance?
Therapy can help understand attachment patterns and restore a sense of self-worth that may be damaged by emotionally draining sexual experiences. Attachment patterns describe the way people relate to themselves and others, shaped by early experiences, relationships with parents, and feelings of security or insecurity from childhood.
Meditation can also support self-confidence and emotional resilience. Journaling and affirmations are additional tools. “Positive self-talk is incredibly powerful and can change the way you see yourself and the world around you,” says Suwinyatichayporn, explaining that research supports this.
These practices can help women regain confidence, avoid burnout, and make clearer decisions about their sexual experiences.
