I am not the right person to ask this as I am fairly bad at using dating apps, social media etc because I find the whole charade too much of an effort. It's too draining and tiring to capture my life and try to project it in a glorifying light, hence my average success rate there. Any advice I give may or may not apply to your circumstances in terms of how do you find someone.

Everyone with decent horizons holds some curiosity for exploration and once you know the person, trust them - I think it becomes easy for people to feel comfortable enough to open up about their darkest fantasies and make you a part of them. It's a blessing if their fantasies turn out to be compatible to yours.

Usually platforms like Reddit serve as a good ground for finding people with common interests. It's just that you gotta take some time to weed out the creeps and the pretentious folks who are just jumping the bandwagon to have some sex and dish out physical/emotional abuse in the name of kink.

In my case, it so happened that the people I befriended turned out to be submissives or they were folks with broad horizons who were open for sexual exploration. Example: Back when I was about to start exploring Dom/sub dynamics - I didn't have much clue. I didn't have a kinky partner to start with either. Then my FWB/close friend told me that she's also curious about kink and would like to explore. We read up a lot together, shared articles, shared stories/erotica and started practicing that in comfort of each other's company.

I advise that you read up on kinks, BDSM and it's conventions online. Read eroticas to broaden your sexual horizons. Read about experiences of people online to feel inspired or to take note of things to be mindful of. This all will help you build your perspective.

Communication is the key to everything be it finding partners or exploring with an existing partner. It just enriches your life, relationships and physical chemistry so much.

I feel that these days a lot of folks are open to it. I am just making an assumption based on your username- if you are a woman, you will have a problem of choice and not a problem of options. :)

TL;Dr - Find people you desire and you are comfortable with. These can be the people around you or if not then you will have to resort to online platforms such as reddit. Test the waters, know about their fantasies and kinks. Try to weed out the bad folks to the best of your capabilities and take the leap of faith when you feel right. Explore with them to grow kinkier together. Ensure your safety before getting into any scene. Discuss meetups and the like with a friend if required. In case you made a bad choice then it's alright to take time to rebuild and start over again. Stay safe. Stay kinky. :)
