hi, i am a 16 y/o male and i am uncircumcised. whenever i rinse my penis with warm water i have the urge to pee, which is normal. the problem is; when i do pee, (and this is all while in the shower) my urethra stings BAD and i don’t know why because the internet says i should wash it with warm water and i do and that happens. however, i have been washing it with cold water now because it does not burn after i pee. can you help explain what is going on and if i should get checked for this?
