###Human: There is a reddish-sticky part on my foreskin even after having medications. Why? ###Assistant: Hello. I understand that you are concerned, but I can assure you that in the photographs there is no feature suggestive of any cancer. I understand that you had a blister after intercourse, that might be friction blister as other cause of blister in genitals include herpes, but that present as multiple tiny blisters. Recurrent glans rash can be candida, but right now, I cannot see any changes. It might feel sticky and thin after healing of a blister for some time, but there is nothing to worry. And certainly, there are no features of cancer. Just use some good moisturizer or use the following. 1. Cetaphil moisturizing cream.
