When i exercise such as jogging, swimming, weight lifting, football anything to do with exercise causes my?
This is normal. You have nothing to worry about. Blood is indeed pumped more rapidly and at increased pressure around your body when you exercise, but the body has a mechanism to direct it to where its needed. When you exercise much of the blood circulation is directed to the muscles you are using, when you have had a big meal it is directed to the gut for digestion etc. When you are sexually aroused it is directed specifically to your penis which become erect. During exercise you dont need as much blood to your penis and gut, so it goes to your muscles instead. Keep on exercising, it is the best way to stay fit and healthy.
