My Girlfriend is really hot. She recently told me that she had some text messages from this guy that a friend had passed her number on to. They were telling her what he wanted to do to her. At first, I was annoyed. Then, I thought about it and the thought of another man shagging my girlfriend started to turn me on. I was tempted to text the guy and get him to tell me what he would do to her. I also thought about sending him some naked pictures of her. I often sit and pleasure myself over the thought of her with someone else. Last night, I pleasured myself over the thought of her being with five or six men. Should I be having these thoughts?
