I'm near 15 now and I've only just learnt that I was supposed to pull back my Foreskin during Sex-Ed, and that most kids could do it at 3 years old?? I'm very concerned as my foreskin is pretty small and probably cannot be pulled back, i've tried and the top barely showed, and the skin hurt like hell. Please give some advice? Thanks
It's not true that most kids can do it at three years old--usually the glans sticks to the foreskin before puberty.
You will almost certainly find that stretching it sideways every day (better, twice a day) will gradually loosen it, but expect it to take several months. Never overstretch--you never want to tear the skin, just stretch it as far as it will comfortably go.
