Using Nighttime Emissions as a Measure for Lock Up Lengths

It has been argued that if a man avoids interrupting his cycle through masturbation or intercourse, then the time between his nocturnal emissions serves as a reliable indicator for setting his chastity lock up periods. I completely agree that our body and nature will handle things on their own; we don’t need to force an ejaculation just for health’s sake. So I have two questions: Is the question of “how long?” something we should really leave to Nature? And, if I go without any wet dreams—no matter how much time passes (I’ve gone over four months)—does that mean I don’t need to be ejaculated anymore? David
