Hi doctor my question is that i have a problem of shaking my penis everyday can it cause me any health problem or aids/hiv anything?

No: I do not know what you mean by shaking your penis? Do you mean that you masturbate every day? Even if you do, it is not going to cause any harm to your health. It certainly will not cause aids/hiv.

Enjoying your body: At your age, almost all your male friends are bringing themselves to climax this way, frequently, like you are. You're supposed to enjoy it. It will not cause you any health problems, and it will keep you comfortable, able to focus on other things, and will prepare you for adult life. Jerry, you should be proud of and pleased with your changing body. You might even talk with Dad. Best wishes.
