if you go on a camping trip for a week or whatever, is there anything you could do to prevent having a nocturnal emission?
If your seminal vesicles are not full, you won't have a nocturnal emission. Therefore, some guys purposely ejaculate just before a time when they don't want a wet dream to decrease the odds of having one. Otherwise, plan on the fact that it may happen. Keep an extra pair of underwear nearby your sleeping bag so that if you do have a nocturnal emission, you can change while remaining in your sleeping bag.
