Is it normal for my penis to shed strange skin out of thepenis hole

I'v had a penis all my life, no idea what it is that you're describing. You might want to do some research or see a doctor.

I got the weird visual of a cobra shedding its skin..

See a doctor, its gonna fall off

See a doctor now!!!! This might be an STD!

Maybe you are peeling.

it comes out of the penis hole. my penis is large

I'd ask your girlfriend about it if I were you.

Yeah i'd see a doc, especially if you're sexually active.
