I wonder why men's penises always smell like feces.

Penis sweat contains bacteria that can cause a distinctive odor, which sometimes resembles faecal matter. This can be especially true in humid conditions. Additionally, the natural moisture of the penis can also cause bacterial growth, leading to an unpleasant smell.
