sounds like you have a yeast infection. any increase in smegma is suspicious. any over the counter stuff for women, like monistat, should work fine.
as far as uncircumcised guys and AIDS, don't believe everything you hear. medicine is always trying a smear campaign on the foreskin, otherwise, it would eliminate a stream of easy money. if circumcision really helped prevent AIDS, the US infection rate would be very low, and instead, it is among the highest in the world.
enjoy your foreskin. you are a lucky guy.
