Well I know soap particles can get caught under the foreskin and over time develop a very cheese like stench.
Another is you just don't good hygene.
Besides these 2 reasons go get it checked out.
am not circumzised...but only past one month my penis get smell like this.............a small thing like pimple not actually papule but it was gone and after it was gone i smell somehting bad in my peni.its bad bcoz i need to change my underware and shorts bcos its stinct....i have never beeen tested with any stds.......
are you not circumsized? I knew a couple of guys with the same type of thing, the folds of skin cause sweating etc.. what do you mean by pimples? I think you might mean pearly penis papules which are extremely common and not std related. do you have any discharge or anything? and have you been tested for all stds?
