Essentially cause they viewed me as a commodity and expected me to completely mold myself to their desires, and pretty much disregard my own comfort level and boundaries.

I get that single guys are a disproportionately large part of the lifestyle. And that, as a single lady or sometimes a couple you have your pick of guys. But there's a difference between inviting someone to your bedroom as a playmate you have basic respect for, no matter what the nature of your fantasy is. And pretty much treating a person like a piece of meat or body part for your pleasure, in actuality and not within the scope of a fantasy.

She claimed to be a professional cheerleader for a sports team, and she had the certs/pics to back up that claim. But she/they tried to bludgeon me over the head with how "lucky" I would be to hook up with her, and how, despite repeatedly drawing my red lines, they insisted I ignore them for the chance to meet up. So I dropped them like the shitty human beings they came across as.

So, as a lesson to pass on to others, have the self-respect to walk away, say no and be true to your boundaries, limits, standards, etc. Whether you're a lady, single guy, couple or however you identify. Someone who disregards your comfort level to focus or emphasize you satisfying their desires, isn't worth giving the time of your day.

Also, if as a couple, or single guy/lady, this is how you truly view potential partners, you might want to reassess how you view other human beings. If it's a genuine kink you both are into, then at least there's that level of understanding. But if that's how you genuinely approach people in the lifestyle, I'll say it as bluntly as possible; it's fucked up, and you need to re-evaluate your mindset.
