If you are unable to last long during intercourse, it can sometimes happen due to stress, anxiety, lack of control, or sensitivity. Practising techniques like the start-stop method, deep breathing, and pelvic floor (Kegel) exercises may help improve control over time. Maintaining a healthy lifestyle, reducing stress, and having open communication with your partner can also help. If the problem continues or causes concern, it is advisable to consult a doctor, who can guide you on suitable treatments or therapies.
