hi Islanerguy, your OK but you have not been washing behind your foreskin, it needs to be done daily, and if you wash/shower more than once a day then do it more, the cleaner we wash our p***s's the healther it will be.
The white stufvf is called smigma.
Good Luck
Visit your doctor to get treatment . other wise it can be increased to level of itching or smell.
