I have a foreskin and wouldn't be without it. At age 65 i, although i no longer get an erection, am still able to masturbate & ejaculate using the »crystal ball« method. This is where you grasp the foreskin with the thumb & forefinger, and manipulate the rest of the skin over the head with the fingers of your other hand. Gives a nice sensation & you cum within a few minutes. If i had been circumcised none of this would be possible. p.s. It helps if you have a fairly long foreskin. Since i've been using this method since about age 5 it's pretty long.
