bartoshek is absolutely right that this is a song about having a baby. But more than that, it is a song reminding young women that their sexual desires are directly tied to taking part in the "miracle" of creating new life: "When May is rushing over you with desire to be part of the miracles you see in every hour." May is hook-up month from the beginning of time (hence it is the month of proms and mayfairs). This song is telling young girls to cherish the memories of their youthful, burdenless sex lives when they are older because it is an experience which will (should) only happen once as life moves into adulthood and parenthood.
