Premature ejaculation is a common sexual issue where a man ejaculates sooner during intercourse than desired, often within a minute of penetration. Causes can be psychological, including stress, anxiety, or relationship issues, as well as biological factors like hormonal imbalances or heightened sensitivity. It can affect both sexual satisfaction and self-esteem. Treatment options include behavioural techniques, counselling, and medications to help delay ejaculation and improve sexual performance.
