Is it normal to have rape fantasies?

First of all, I am respectful towards women and human beings in general. And I will never act on my rape fantasies. Maybe roleplay, but I am not the kind of person who breaks the law. In fact I am quite fastidious about following the rules because I don't like getting into trouble.

Having said that, at times I have had some dark and dirty thoughts. Sometimes I would see a really attractive woman and I would imagine me pin her to the ground and ravish her while she writhes and struggles to free herself. These kind of fantasies aren't very common because usually I am a sub and I like to be dominated by women. But sometimes suddenly these kind of thoughts sneak up on me when I least expect them to.

It happened today when I was getting a hair cut. The hair stylist was new. She kept making small talks but I couldn't pay attention to what she was saying. Her voice was so mellifluous, her skin so creamy white, the kind I like, I just wanted to have my way with her. Again, I would never actually do it. But I couldn't stop my mind from imagining how her voice would sound like begging me to stop, how her body would squirm until she realizes it's in vain and surrenders herself to me and then I violate her innocence as she lies beneath me.

If she knew what was going through my mind she would think I am a monster. But I will never do that in my real life. I wouldn't be able to live with myself.
