I know because i am doing it! Or another healing book. People who self-injure with masturbation tend to be women who use objects that cut, burn, or otherwise harm their genitals while they masturbate. Was to explore other avenues to deal with the shame.

I would then feel guilty and shameful about binge eating, telling myself i was a fat cow and a terrible person for eating so much food.
