I wanted to ask if it is normal and if many other guys experience the same thing. Some curvature of the penis is normal in men. Chances are good that you are completely normal. Despite the airbrushed, computer enhanced photos you see in magazines, most human bodies are not perfectly symmetrical. Most of us have asymmetrical breasts, ears, eyes, feet, etc.
Most men have one testicle which hangs lower than the other inside the scrotal sac.
And few erect penises are straight as an arrow. You didn't mention how severe the curvature is or if it causes you any pain. I suggest you visit a physician to put your mind at ease. A French surgeon, Francois de la Peyronie first described the condition in 1743. It is characterized by a plaque, or hard lump that forms on the penis.
