I noticed that large patches of skin around my anus, between the buttocks and on one side of genital region (scrotum) have darkened in colour dramatically compared to the surrounding area. It wasn't this dark before. In addition some days the skin in the region has a different texture and is scaly. Overall that region is really itchy and it doesn't seem to be a case of dry skin because I tried various lotions and Vaseline. It seems to be spreading. I have not smoke or had any sexual intercourse at all.I appreciate any help. Thanks. If you need pictures to see what I am talking about let me know.
