I did a graduate research paper on fetishes/kinks and their history, etc., so what I’m saying is coming from just being a human, but also knowledge I gained from the community through research and interviews.

First off, be honest with your partner. You need to have a genuine conversation about how you feel, your comfort levels, all of it. Something like this needs to be shared, and there needs to be a strong understanding between both parties. It’s called a partnership for a reason.

If this is something you feel you can proceed in, I HIGHLY recommend you draft a legally binding contract regarding this specific kink. I’m not saying they will, but people can make accusations when they’re upset, and you don’t want this to turn into something that could harm your reputation - especially because this kink is very delicate. Having clearly defined rules, safe words, guidance from your partner, etc., is key. Contracts like this aren’t unusual in certain fetish communities, and it would be beneficial for you both to have everything not only written down, but consent placed in a document that outlines boundaries specifically.

Finally, I’d suggest you do a lot of research on this. You need to understand what you’re getting into, how it works, and how you two can work together. A kink isn’t fun if one party finds it unpleasant, and feels pressure to do it.

If this is something you don’t feel comfortable with, say so. This may be one area where things just aren’t going to work out. You have the right to say you feel uncomfortable, and that should be respected. Don’t stay if there is pressure. Sex and kinks should be fun for both parties, and this isn’t something you should feel you have to do in order to make them happy. Your comfort matters a great deal, especially when it comes to things like this.
