You have a nice uncircumcised penis that is sure to be good for masturbation. With a frenulectomy, you can increase the mobility of the foreskin. This is even better for masturbation. Then the penis would not be so crooked when the foreskin is fully open. I am writing from my own experience as a habitual masturbator. I removed the frenulum preputii myself. Do you still have your frenulum?
