Suggest Remedy For Foul Smell In Penis

I have quite a strong odor coming from my penis. I'm uncircumsized and I have no signs of an STD or infection of any type. Everthing looks, and feels normal. There has always been a smell, but now it's stronger and not very pleasant. I shower daily and wash it well, but the smell comes back after about an hour or so. What do I do?
