Unless the pain is caused by something that causes real damage to your body, which is kind of unhealthy (since "health" usually NOT damaged,) but isn't it more unhealthy to deny your feelings and damage your mental health? Even damage from extreme playing will heal in an otherwise healthy body, but from some things the mind, the heart, the soul never recover. I wish I were walking around with bruised butt and a small cut from bloodplay with my love, rather than the cold soul and breaking heart from being apart from him (we are long distance, and he's just gone back to school, so we aren't having much contact time of any kind right now.) Try to keep yourself safe in your pain play, and revel in your mental health!
