I'm uncircumcised, and I have found out about washing under foreskin and pulling back about 5 months ago, I'm 15. First my left side was white (it's not white like a paper, it's a bit transparent white, I don't know how to say that. English is not my first language)
I also couldn't pull back my left foreskin side (I can't pull back completely right side too, and I'm not trying to because it's uncomfortable)
I've seen some yellow creamy stuff on the left side under foreskin, It very easily comes off. Right side was fine. When I touched the left side it hurt much more than the right side.
Now my right side also is getting whiter but I haven't noticed any pain change (I feel pain only when touching) that hole in the middle of glans from which I **** is red (sorry for my english xD). I don't think it's normal, my glans should be pink if I'm right.
I'm not washing under foreskin because it's very uncomfortable, and someone said on the internet that he lives 30 years without doing anything with glans and he's alright, he said he is sexually active.
I do masturbate nearly everyday.
