Hi. I'm 14 and I recently noticed that my erection is crooked to the left side, it isn't bad but I really want it straght. I think that its always been like that but now its gotten worse because I masturbate frequently with my right hand. Can I fix this by masturbating with my left hand? Or some other way?

It's natural to curve in one direction or the other. It has nothing to do with masturbating.

If the curve is severe, yes, it could be a medical condition.
