Premature ejaculation, low sexual stamina, and occasional difficulty in maintaining an erection may be caused by stress, anxiety, performance pressure, lack of confidence, unhealthy lifestyle habits, poor sleep, smoking, alcohol use, or underlying medical conditions, such as diabetes or hormonal imbalance. The clear fluid you notice during foreplay is usually pre ejaculatory fluid, which is normal and produced by the body to lubricate and does not indicate any disease. These problems are often treatable. Lifestyle changes such as regular exercise, a balanced diet, good sleep, and avoiding smoking or alcohol can help improve sexual health. Techniques such as the stop-start method and pelvic floor muscle exercises may help control ejaculation. Reducing stress and improving communication with a partner can also be beneficial. If needed, a doctor may prescribe medicines to improve erectile quality or delay ejaculation (such as sertraline and dapoxetine) after proper evaluation. It is important to consult a doctor for personalised advice and to rule out any underlying medical condition.
