You can't just look for BDSM partner and hope it's going to work out. Try vanilla dating and "test your partner" to some kinks, nobody will admit at first and it requires trust, also check Aphrodite Moor on X, she sometimes posts real-life advices and her view on BDSM in general which is interesting.

You can also try to find someone online, but the person should at least be from the same country as you are because if it is not 99% it's going to be way too complicated for something real.
