Great question, I don't participate in it right now being single, but I believe that doing a lot of research and getting as much knowledge about your interests is the best place to start. Afterwards if you are of age (18+, that's the age to safely be able to consent to BDSM acts globally) going out and meeting other people in the community in person is a grest way to start. Hope that helped, always stay safe and consensual :)
As someone who participates in the same world of Dom Sub kinda thing, I was very happy that the end showed them in a happy healthy relationship. So many manga with S&M in them always have unhappy endings showing this often times most caring and trustworthy lifestyle in a bad light.
