Re: How far can a male pull back his foreskin?
I can pull my foreskin back behind the head until the frenulum is fully stretched. For me that means that the foreskin is streched pretty flat down the erect shaft. I guess how far you can pull it back depends on the length of the frenulum. You don't want to tear it. If you can pull the foreskin back behind the head when you are erect you are fine.
