Sexual dysfunction caused by one-night stands should not be underestimated in terms of psychological resilience.

**Sexual disorders caused by one-night stands**

**Case Study**

**Name: Lu Yonghong (pseudonym), 42 years old**

**Region: Beijing**

**Occupation: Teacher**

Mr. Lu, 42, is a model husband who is disciplined, law-abiding, family-oriented, and responsible.

Not long ago, after drinking heavily with friends one night, he had a one-night stand. Since then, he hasn't slept for three days. Although he confessed to his wife with extreme remorse, his psychological pain didn't lessen; he felt unwell all over and suspected he had contracted a sexually transmitted disease. This has caused him constant anxiety, affecting not only his work but also his ability to have normal sexual intercourse with his wife.

Di Xiaolan, director of the Sexual Psychology Clinic at Beijing Huilongguan Hospital: Many men, after growing tired of the mundane routine of married life, often hope to have another "beautiful" one-night stand, and naively believe that an occasional affair will not have any serious consequences. However, the psychological impact of an occasional affair on a man can be a significant decrease in libido.

It's not uncommon for men like Mr. Lu to experience psychological distress and problems in their sex lives due to a one-night stand. Often, men overestimate their psychological resilience, believing a one-night stand won't affect their lives. However, psychological issues can sometimes lurk beneath the surface of everyday life. Those who cheat may experience milder forms of anxiety about being discovered by their spouse, viewing it as a permanent stain on their reputation; others, like Mr. Lu, may suffer greatly from extreme self-blame and other serious consequences. Therefore, setting aside family responsibilities, when a man's "infidelity" begins to stir, he should first consider whether he can bear the potential negative consequences of infidelity.
