Hi,

I have been diagnosed with psoriasis and even though it is not too bad of a case, it has spread to parts of my body such as my legs, arms, behind my ears, and my penis. I guess my question is: is it normal to have it there? the area is between the head and the shaft (lack of a better word) and what happens is a layer of skin (looks dead) grows and stays there but can be easily ripped off without hurting. If i masturbate without any lubrification the area around it also breaks up looking like very dry skin.. but if lubrification is used than the dead skin just comes right off and the red, oily skin or flesh under it is exposed until another layer grows on top of that.

I just want to make sure that it is normal for psoriasis and if there are any specific treatments for this part of the body.

thanks for the help
