The skin on my penis below the head is ripped and if I pull it back it will bleed what should I do?

See a doctor. I can't stress this enough. If there is skin that you can actually move, or if even moving it causes bleeding, then you need to see a doctor.

Dude, you do not want to risk not seeing a doctor. Trust me. It doesn't matter how it got ripped, just see a doctor.

Ooh, I've seen how much that can bleed!

I'd say if it hasn't healed within three days see a doctor.

If you had simply torn it during sex, or by masturbating, I wouldn't worry too much.
