Dear doctor, Sometimes I get semen leakage while bowel movements. Is it normal or something to worry about. Your advice would be greatly appreciated?

That is fine. this is common in a young man who may be having a difficult bowel movement or just has a lot of semen on board.
No worry. What you described is nothing to worry about. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
