Dexter has this as well on his little wee wee...I asked the vet when we were there for something else and found out as well that it's normal. However because it does gross me out, even when he cleans himself (I can't stand the gross noises that are made when he cleans himself....talk about gag!), anyway...I make sure when I bath him I clean his little wee wee with a wash cloth very well, I do this about once a month. After all something that has build up/or drainage like that is bound to become something worse if it's not taken care of at least once in awhile.
