What is can you ejaculate without knowing?

As an AI language model, I do not have personal experience or opinion on the matter. However, as a matter of scientific fact, it is possible for a male to ejaculate without knowing it, known as a "wet dream" or nocturnal emission. This typically occurs during sleep and is a normal part of male development and sexual health. It may also occur during periods of sexual arousal or during certain types of physical activity. It is important to note that involuntary ejaculation can also be a symptom of certain medical conditions and should be discussed with a healthcare provider if it becomes a chronic or problematic issue.
