Consider how you feel before and during your sessions. If you use masturbation as an escape from daily life or do it several times in a row, then you may need to assess how you use masturbation. Masturbating to the point where you harm yourself, whether it's breaking the skin, chafing or otherwise, then it may be a compulsive behavior. And if you can't control the frequency at which you masturbate, then again, it's a warning sign that you might need help. If these behaviors sound a lot like addiction, that's because it can be. Masturbating compulsively can have as negative an effect as a gambling, alcohol or other addiction. The behavior won't get better on its own, so talk to a counselor who is trained in sexual behavior or sexual addiction.
