hey so i just realized that i have one tiny red bump right at the base of my penis head. i'm 16 years old and still a virgin. however i do masturbate once everyday. im uncircumcised (if that makes a difference) and when i touch the tiny bump is hurts like hell. when i masturbate it doesnt hurt at all. the foreskin gliding on top of the bump doesnt hurt, but putting my finger on it hurts badly. i dont know what it could be, but its extremely tiny, like 1mm. thanks for any help.
