10 General Symptoms of Personality Disorder

6. Change in Sexual Habits

Personality disorders can cause shifts in sexual behavior. Some people may lose interest in sex altogether, while others may become more sexually active in ways that feel risky or out of character.

For example, someone might seek frequent or impulsive sexual encounters without thinking about the consequences. This kind of behavior is often linked to borderline personality disorder.

Both a lack of interest and a sudden increase in activity can affect relationships and emotional well-being.
