I discovered hypnosis a decade ago while I was in high school and have participated in the real-life community for six years. I dated Shibby a while ago and introduced her to this kink. So yeah, I've actually thought about it a lot.
The way I see it, we have emotions that once played a role in our survival as a species that we no longer require in civilized society. We rarely feel them because our environment doesn't bring them out. Dominance and submission are great examples; tribes of people no longer conquer each other like they once did, so those feelings remain dormant most of the time. In contrast, dogs feel submissive because it's advantageous in our society.
We're not weak or damaged people. We're experiencing an emotional state that's unfamiliar to us for recreational purposes. Dominance and submission are distinct, intimate feelings that can be very enjoyable with a partner you're comfortable with. Being hypnotized often feels similar to submission, so they make an excellent combination in the context of role-playing.
If you enjoy hypnosis, I encourage you to find a partner who's open to dominating you. It's not necessarily about whips and chains. It's about convincing both of you who has control, and once you've fully accepted your roles, it's an intense emotional experience. And then it often turns into passionate sex ;)
