I've been following this since the beginning, listened to the podcast and read carefully everyone's opinions and experiences.
I am extremely interested in kink from a feminist perspective, having only in the past couple of years realising I have kinks. I haven't made an opinion up about it yet, but I do want to add my thoughts. I don't want to conflate the kink "scene" and the ease of access to abusing individuals, with my own personal kink and sex preferences and choices in private. How I go about wanting to behave or fulfil my desires is up to me. So far, I have only dipped my toe in the scene publicly in the past year, and it has always (for me) been a very safe space to be, but I have witnessed some very unsafe practices.
My interpretation of kink is multifaceted. There is the power dynamic, which needs to be agreed with full consent (this includes whether you're under the influence of drugs/alcohol/ knowing you are physically and mentally well enough to engage and consent in the practices of your choice). A safe play partner also has to have awareness of those aspects so they are sure you are fully consenting. And vice versa. But ultimately your boundaries lie with yourself.
By having kinks like sub/dom, being tied up with rope etc, means giving up a part of your power and that can be liberating, having less choice. Like a restaurant menu with too many options can be overwhelming, having limited choices causes less anxiety, and transferred in a sexual sense this may be cause more pleasure.
Kink for me is a form of free play, a thing for doing without an necessary outcome, within set boundaries, not necessarily "rules". However, you may have your own hardline boundaries that stop the play, or soft ones that are fun to try out and see if you like it not. I then reflect afterwards and say, yep, not for me. I like to explore this side of myself, but I am not defined by it.
Lastly, humans have similar experiences for enjoyment, it's just that kink has crossed this into an added layer of sexual pleasure. What is the difference between contact sports (rugby, say) and getting hurt and damaged, hitting the wall in running a marathon, and being spanked in a sexual context? What is the difference between people wanting to be exhibitionist on reality TV, or being exhibitionist in a sexual context? Voyeurism as a person watching the car crash TV of love island or big brother, and voyeurism of watching someone else have sex.
I get the feeling that a lot of kinks, especially the scene, and unsafe practices are a result of the patriarchy and porn. That this is what you're supposed to like. Just like wealthy success could look like owning a yatch. Do you actually want the yatch? Or do you think you do and want to signal to the rest of society you've made it because you have a yatch?
Anyway, I'm still learning. Keep adding to the thread! I could be completely wrong in my thinking and am open to my mind being changed.
