Why is a comma often used after "sometimes"?
Does that mean a comma is necessary after every use of "sometimes"?
Not necessarily. It depends on the context of the sentence and how "sometimes" is being used. If it's being used as an adverb to modify the verb, a comma may not be necessary. But if it's being used as an introductory word or to indicate a contrast with the rest of the sentence, a comma may be appropriate.
