it seems like the majority of people have some sort of curve in their penis, including me. mine curves to the left as well. i read something once and in a way it makes sense. are u right handed? i read somewhere once that if ur right handed, the way that u sometiems push on the ur penis while ur masurbate w/ ur right hand, can with lots of time, make ur penis slightly curve to the left. and vise-versa w/ left handed people. idk if thats true but it kinda makes sense, not to worry though. like i said, most people have it and it doesnt matter, the only time it can be bad is if it curves so much that it would hurt to have sex because it has to go relatively straight, but it would be VERY rare for someone to have that much of a curve in their penis, dont worry!
