Is it normal to have wet dreams?
Yes. Wet dreams are a normal part of puberty and can happen whether or not you have ever had sex or masturbated. They are not a sign that you are doing anything wrong, and they may stop happening or become less frequent as you get older.
What this does and does not tell you
This is general information, not a diagnosis. Only a clinician can examine you, take your history and run tests. The same symptom has different causes in different people.
If something is sudden, severe, or getting worse quickly, get medical advice rather than reading on.
