Pubic And Penis Rash

Ok for at least 5 month there has been a lot! Of itching in my pubic region it has slowly spread to my penis and now the bottom of my penis itches. There is alot of swoleness and flakeness, wich I believe is dead skin. It is also a little red. I have never had sexual or oral contact or anything of that sort. Ive tried some anti itch creams( wich don't work to well) and have washed my pubic region and penis thoroughly. The washin seems to help a little bit but the itching,flakes of dead skin, redness,swoleness just come back.

Can someone please tell me any info. About what this is. Or anyways to get rid of it.

Ive been thinking it could be scabies or crabs.
