Hello
You can relax now. As you age, you may notice a few differences in your body--like less hair, etc. A slight curvature of the penis may be caused by some calcification and is not a cause for concern.
Some penises are completely straight, some curve up or down, and some curve to one side or the other. All of these are simply physical variations—like the difference in peoples’ noses. The only time to be concerned is if your penis begins to curve so extremely that it’s difficult or painful to be sexual with a partner. If this is true for you, you should see a urologist for diagnosis and treatment. Otherwise, stop worrying and realize that with age comes great wisdom as well as a few physical surprises. Keep yourself healthy, and there's no reason why you can't enjoy your sexuality throughout your whole life. Dr. J
