I recently noticed that the tip of my penis (on the right side) was shaped slightly different than on the left side. I also noticed that when measuring my penis, it was longer when measured on the right side, most likely because my penis curves to the left. All of this left me to believe that years of masterbating with my right hand has affected my penis' symmetry. With that said I decided to start using my left hand to masterbate, in the hopes that it will straighten and even everything out. And all I have to say is WOW...ever since I've been doing it this way my orgasms feel really amazing and I ejaculate more. I think for years there were nerves on the left side that weren't getting any attention and now they are. I also noticed that doing it with my left hand feels like I'm touching a penis for the first time - I guess my right hand was so used to it that my hand had lost the sensation. It almost feels like I'm jerking off someone else. Has anyone else out there experienced any of what I've talked about?
