Sexual difficulties during intercourse can happen for many different reasons. In many cases, both physical and emotional factors play a role. Stress, anxiety, depression, or problems in a relationship can affect sexual performance. Health conditions like diabetes, high blood pressure, or hormonal changes may also contribute. Some medicines can have side effects that impact sexual function. In men, low testosterone levels or reduced blood flow can be involved. Lifestyle habits such as smoking, alcohol use, poor sleep, and lack of regular physical activity may also worsen the problem. This condition is often treatable once the cause is found. It is advisable to consult a doctor for a proper evaluation and basic tests. Simple lifestyle changes like eating healthy food, staying active, getting enough rest, and avoiding smoking and alcohol can make a real difference. Stress management and counselling may also help. If an underlying medical issue is present, a doctor may recommend specific medicines, hormone therapy, or psychotherapy to improve sexual health.
