I I am 15 and are unable to pull my foreskin back I am worried about stretching it as I don't no how to do it
Hi guest,
It's normal for you to not to be able to pull your foreskin back, until about 16 or so.
Get an erection and pull down on the shaft skin so that the glans spreads the opening of your foreskin - OR - use your fingers to spread the opening. It may be easier to do in the shower, the warm water can help soften the skin. The more often you do it the sooner you'll notice results.
Hope it helps.
