Peeling Skin

It feels really weird admitting this, even if it is just on a form for others with pica, but I want to get this off my chest. I've had pica for as long as I can remember, and even when I was a child I would peel off my skin and eat it. It would never be much, most of the time I would just chew on my chapped lips to get it, but it has snowballed over time. 
Even as I type this, the coppery taste of blood is present in my mouth. The insides of my cheeks are in a horrible state, but I can't stop myself anymore. It's not pleasurable, but... I guess I feel like I have to. I would compare it to a strong, uncontrollable compulsion, like seeing something that's so close to being perfect, but something that can easily be fixed is off, ruining the entire image. 
I've managed to cope for years now, the only problems being an occasional infection and blood getting everywhere. However, I recently started dating a girl; to keep her anonymous, I won't give out her name. I don't know how to tell her about this habit, nor can I think of an excuse for the numerous scars and fresh wounds scattered across my body.
The worst thing being about this, and why I decided to post this, is because she has numerous skin tags. I can't put into words how badly I want to pinch one and start pulling. The thought plagues my mind, and I honestly don't know how long it'll be before I give into the urge. 
Please, if anyone knows what to do, tell me. Every time I see them when she's wearing a tank top, they're all I can think about. The thought of peeling one off was absurd to me at first, but now, as the urge has grown, I might be willing to hurt her so I can finally get the sense of satisfaction I desperately crave...
