Erotic hypnosis is when someone uses their words and actions to put someone else in a trance-like state where they become more suggestible and open to suggestion. This is often used for sexual pleasure or arousal. Think of it like playing pretend or make-believe, where you imagine things in your mind and they become real to you. Except instead of playing with toys, you're playing with your thoughts and feelings. However, it's important to note that using hypnosis for sexual purposes without someone's clear and enthusiastic consent is not okay and a violation of their boundaries. It's important to always communicate and have mutual agreement before engaging in any form of erotic hypnosis.
