After im done masturbating i cry why does this happen n is it normal?

No one knows better: You are probably the only person who could know why you cry. After masturbating or any other time. I imagine that the release of energy that can be part of an orgasm lets your feelings flow freely. Perhaps there are painful or sad feelings inside you that usually are held back . Yes, i think it is normal - don't worry, but if you want, you could talk to a therapist about your sadness.
