Hi sorry but im going to ask you to see your family Dr , Please don't be shy its not awkward at all Dr's know what you are going through and help accordingly ,regards the white discharge that wants looking into also , Please go it will give you peace of mind , take care ,
the white stuff is dried c u m, try cleaning your inside
The white stuff is probably smegma. Smegma is normal and harmless, but needs to be washed away once in a while. Since your foreskin does not retract, you may use a rubber bulb type ear syringe to flush it out. Just fill the syringe with luke-warm water, stick the nozzle into your foreskin, squeeze it and the water will squirt up into your foreskin.
