I have to agree. Guys shouldn't smell down there. I personally was circumcised as an adult, it was my choice. Even though I constantly keep my penis clean, and I mean I cleaned it every time I urinated, there was always that "musty" smell. Even though there was no medical condition or disease, I personally feel that the circumcision was the best thing I ever did to my penis.

As well, it's not just the penis, it's also the amount of pubic hair. A guy that keeps it trimmed or shaved has a lot less "scent".

I personally am very considerate when it comes to being clean down there. Seeing as how I'm bisexual, I keep my penis as clean as I want the penises I put in my mouth.
