No joke, if you are uncut washing your glans with soap will make it smell worse. It upsets the bacterial balance.
I got into this vicious cycle whereby I would find I had smegma and stank penis just hours after washing, so I would wash again, then it would smell bad an even shorter time later and so on.
Now I pump before a shower, and in the shower just wash off the leftover lube (no soap used). It never smells bad now, and no smegma. Soap is a bad thing to be using on your penis.
