Look, if man has sex regularly, and he's not circumcised, etc, and he doesn't at least keep that area clean once a day, preferably at the start of the day, or in the morning, etc, and then almost right after every single time he has sex also, etc, and doesn't make sure he pees at least once right after every single time he has sex, etc, then that uncircumcised man will have problems "down there", etc... And it is also important that he does his best after every single washing, and/or peeing, etc, to keep it as dry as he can also afterwards, etc, and as dry as he can almost all of the time, etc, as the moisture being kept in can cause problems also, or be a breeding ground for problems (bacteria, infections, etc) also, most especially if it's not being kept clean, etc...
And when he's a boy, maybe right around puberty, as some have suggested, etc, anyway, once that foreskin is pulled back, etc, if he isn't taught almost all of these things right away, etc, he will have problems with bacteria and infections, also yeast sometimes, etc, and then if when he comes to the point when he's having sex regularly, etc, and he's not doing all that I just said, etc, and also all of what I just said up to this point already also, etc, when he starts having sex, if he is not already in the habit of these things, etc, and does/doesn't already know and is doing all these things, etc, then not only do bacteria and infections and yeast come into play, but then also at that point STD's, and possibly being a carrier and spreader of STD's, etc, if He is not doing all of these things regularly, etc...
Circumcised men have a whole heck of a lot less problems with this in general, etc, their area is, and always kept and stays dry, etc, and it's very easy to clean and take care of and/or keep clean, etc, to the point where he really doesn't have to even do it nearly as much as the uncircumcised male does, and in fact, not even close to what the uncircumcised male does, or has to, etc...
Anyway,
God Bless!
