Hi, i'm 16 and uncircumcised. I just recently started to pull back my foreskin, as it is very tight. Anyways, my penis head is very sensitive and hurts when it comes in contact with anything, the opening of my penis is also very red. Are there any treatments I can do to fix this, or should I see the doctor? Also, in order to prevent this from happening again, will I need to be circumcised?

Thanks.
