In this age, men usually get a whitish or slightly pinkish spots over the foreskin or the corona of the penis. These r called benign penile papules.
They usually disappear as u age or just after marriage.
But be sure u r not exposed to any kind of sex, before considering ur lesions to be benign papules.
If u have some sort of sexual history, Kindly do a profile of investigations for STIs.
If u have no such history, then nothing to worry. Just keep ur glans
and foreskin of the penis clean and dry after every micturition.
