thanku for your query,
well i understand your concern, but nothing to worry about .It seems penile papules , which are skin coloured and causes no discomfort . Apparently there is no cause to the occurrence of these papules.
.But if u see any discharge from these papules eg yellowish discharge, than it is a sebaceous cyst
. However seeing the doctor, will provide u a clearer picture.
I hope i have answered your query
