🤔 you're telling me a man who likes having sex with women is finding himself sexually attracted to a young woman that's isn't his direct relative? Yeah that's weird. /s
Yeah you're going to have to control yourself, maybe dive deeper into why you're having these urges/fantasies. If you don't like her as a person, your desire to forcefully have sex/rape her could be a manifestation of your desire to have control over her. Or maybe you don't have much control over your life/situation right now, and you see her as a way to exert control over something?
There are many possibilities. You might also just be having idle thoughts. At the end of the day, there is no thought police, only your words and actions are observable by those around you.
