i am a 15 years old boy . lately I'm getting lower back pain and when I want to urinate I feel like there is something blocking my urine for a brief while, and I get some pain when I ejaculate.I feel shy to tell my Dad. I just Don't know what to do.is my problem serious or not ? Do I need to consult a doctor? Can it be a prostate problem?Thanks any way.

Your dad is the best person to tell him this situation don't be shy he is a man like you and hi knows all the things that a man need know to help you, but if you don't have the courage to this ,evaluate other alternative like the doctor of your school or any friend or family how campaign you to the doctor, in the meanwhile drink a lot of water and cranberry juice this will help your urinary system.

Could be a urinary infection with symptoms like that. Go see the doctor, as infection spreading to the kidneys can cause permanent damage. A course of tablets for 7-14 days should see you better. Don't worry about showing it to your doctor, they see things like this every day. Drink lots of water to flush your system through. As regards ejaculation, at your age, if you are not used to it, you are using a muscle which has not been used in this way before. Maybe it is pain due to the muscle contracting like any other muscle when you first start using it.

it could be a number of things, since you said it bothers you during ejaculation and when you urinate it sounds like a kidney stone, There have been guys as young as 12 with them,The prostate if inflamed or enlarged will be swollen and you will go pee 20 times a day.. if thats the case them yeah go to the doc, and they usually do the old finger massage thing.
