What are the solutions or treatment for wet dreams in night & pe?

Underwear: You won't want to stop wet dreams at night. I'm not sure what pe is, but make sure to wear absorbent underwear when you're up and around and prone to wet dreams. There is no way to stop orgasm if you are anatomically intact. It can be embarrassing if your clothing soaks through, but take precautions including double underwear if it's really an ongoing problem. It will not go on forever. Best luck.
