I am a (since birth) circumcised male. for the first time ever i noticed white slimy stuff that smells. it's right where the shaft meets the head, when my foreskin covers it when flaccid. any ideas?

Keep clean and dry..: Despite neonatal circumcision, few still left with redundant foreskin, which may still "retain" urine between penile head and residual foreskin. For the time being, drain your urethra well after each voiding and keep the area as clean and dry as possible, but avoid over use of cleansing agent and physical stimulation. Further doubt? See urologist for detailing... Best wish ... Always.

Smegma: This is likely did skin cells that builds up which is called smegma. You should cleaned regularly under the foreskin to prevent this buildup. If this continues, you may need to consider a circumcision to cure this problem permanently.
