Possibly. It does say Shemoneh esrei Lechupah. As long as a boy has the right hashkafos and is mature enough he should get married younger. However sadly I have seen young couples in public settings where the boy was 19 or 20 tops (chassidish) and he was ignoring his wife. She looked miserable and was just looking around the place like someone please notice I exist. Many boys just dont know how to be in a serious relationship at that age.
