How to help my mentally ill girlfriend?

[boris255]

I have a 15 years old girlfriend and she watches porno everyday and masturbates. We have sex 2-3 times a day. She wants more but she has to go to school. She looks at my pants and then touches my penis and play with it. When we do homeworks together she writes on her notebook perverse words and she draws a penis on it. And she doesn't do it only when we are together. She does it when she is at school too, during the classes. She likes penis very much. She is a very smart and sexy girl. But she worries me. She is cheating on me and told me about this. She says she cannot be satisfied by nobody. She wants it more and more. She lost her virginity at 12 years old because she wanted to. She didn't be raped or something. She masturbates since 8 years old. I have tried to talk to her about that but she says she cannot live without penis. She behaves pervesely and swears. Sometimes I call her a nympho but then she gets angry. Today when we were at her home doing homeworks she wanted to suck it and she said : "you don't have to do anything, just stay relaxed and let me do my work." Her work?! Some people say she is a slut but I don't think so. I don't know the truth. Last week I didn't wanna have sex with her and she was begging me and I didn't accept. Then she cried like a baby and gone to the kitchen. She didn't come back in the bedroom so I went to her. What have I seen?! She was hurting herself with a knife while crying. Then I wanted to help her but she didn't let me do it. Then I told her to come and fuck with me if she wants it but she couldn't get up. I have bandaged her. Then I raised and fuck her. Please help me. I love her and she loves me too. What should I do?! I am worried. ..
