Why do i get mad or cry after i masturbate? is there something wrong with me?

Guilt: If you get mad at yourself after masturbation it may point to guilt you are experiencing as a result of not believing that your sexual urges are normal or permissible. This is a problem I have certainly encountered before, you may need to speak to a clinical psychologist who could help learn more about normal sexuality and help uncover the origin of your distress. Best.
