Hey, I'm 13 and my foreskin won't go back much at all. Maybe just a little bit to the point where I can see the tip but that's it.
Hi Jacob,
You are NORMAL. It's common for your foreskin to not retract until around age 16 or so. You CAN and SHOULD start stretching though.
Use your fingers to spread the opening OR get an erection and pull down on the shaft skin so that the glans spreads the opening. Take your time, you don't have to hurt yourself. The more you do it the sooner you'll notice results. You will also find your glans to be very sensitive at first - again that is NORMAL.
Good luck.
