What is that white thing behind the glans?

The white stuff behind the glans may be dirt tissue, which is mainly caused by lack of local hygiene and cleaning.

If the glans is not properly hygienic and clean in daily life, it may lead to the accumulation of dirt around the glans, and a lot of bacteria may breed there, which may lead to repeated attacks of balanitis and have a greater impact on physical health. It needs to be cleaned with warm water in time, and at the same time, choose to wear loose and comfortable underwear as needed.

For cases where there is a lot of white dirt caused by a long foreskin, circumcision surgery can also be used to treat it.
