wetdreams

You didn't screw up, but there are things you can do to reduce the frequency of wet dreams if it happens too frequently, for example:

• Reduce meat consumption
• Eat less for dinner
• Avoid overexertion
• Avoid extreme temperatures during sleep (too hot or too cold)
• Sleep on your side instead of on your back (works from my own experience)

After a wet dream, one should take more rest, so personally I don't recommend going to the gym. Maybe you can just go for a walk if you want to stay active. Also, one tends to relapse after a wet dream, so you may want to be more careful, find ways to redirect your thoughts when urges come.

Hope these helps. Good luck!
