Thanks for posting your query.
You have not mentioned in your problem that whether these "acne
spots" are present on the under surface of fore skin or on the glans penis
If the spots are on glans penis then you should not be worried at all as these are known as Pearly penile papules which are enalrged oil glands of this area.
But if these are in the under surface of the fore skin then it can be either of molluscum contagiosum
or initial stage of warts
. You should meet a dermatologist
who will give immediate diagnosis without the need of any test and give the treatment accordingly.
with best health wishes,
