An interesting case. She was addicted to sex, to the point that she couldn't maintain friendships and workplace relationships. It was all but destroying her life. She started getting those tats and it helped her overcome her addiction. It was in Bizarre. Perhaps we are lucky that we have hypnosis?
"Feelings, sensations that you thought was dead,
no squealing... remember that it's all in your head"
She is addicted to sex. It ruined her marriage, and cost her several jobs. She decided to try and stop so she get a tattoo. And it helped, so she has been getting more. The tattoos let out her urge without her actually having sex. She is currently in a relationship with a porn star, but she herself isn't. And if I remember correctly, her current marriage is shaky at best.
She is called Michelle the pass-around girl. You can google it and find her story.
