"mostly met" an adverb preceding a verb = correct
"exclusively, male." correct even in the absence of comma between "exclusively and male" because "exclusively" is an adverb and "Male" is adjective.

Your "

""
mostly fruition" of statutory rape" incorrect.
"
mostly a fruition of statutory rape" "
mostly a result of statutory rape" = Correct, I am really sorry to pop your bubble.
No matter at what pace English grows the rules remain the same: "adverb precedes verb, adjective or another adverb. Adverb will never go before a Noun" sorry to rupture your bubble!
