Premature ejaculation is a common sexual problem that affects many men. There is no fixed time that a man should ejaculate, but it is normally considered premature if it occurs within one minute of the penis entering the partner. The exact cause of premature ejaculation is not known, but it is believed to involve a complex interaction of psychological and biological factors. Some of the possible causes of premature ejaculation include:

• Psychological factors: Early sexual experiences, sexual abuse, poor body image, depression, worrying about premature ejaculation, guilty feelings, anxiety, and relationship problems.

• Biological factors: Irregular hormone levels, irregular levels of brain chemicals, swelling and infection of the prostate or urethra, and inherited traits.

• Physical problems: Erectile dysfunction, unusual hormone levels, and sensitivity of the penis.

• Other factors: Performance anxiety, stress, unrealistic expectations about sex, lack of confidence, and history of sexual repression.

If premature ejaculation happens occasionally, it is usually not a cause for concern. However, if it happens regularly and causes distress to either one or both partners, it is an issue that should be addressed. There are several treatments available for premature ejaculation, including psychological assistance, medical treatments, and behavioral techniques. It is recommended to talk to a doctor or a sex therapist if premature ejaculation is a persistent problem.
