After having been not just part of our community but various other kink communities, both online and in person, it's surprising to me how much of an argument this can be. Just like everything else in life, there is no "right" or "wrong" way to practice your kinks with your partner. The only solid rule I can think of is also what most sane people would agree upon, as long as you're not hurting anyone else, you do you.
That means everyone involved should be a consenting member, IE don't be practicing a kink in public that involves an audience that didn't consent to be your audience. Before all you exhibitionists get in an uproar, I'm an exhibitionist myself and there's a "right" way and a "wrong" way to do it. Limit as many factors as possible of having the consenting audience and the non-consenting audience. There's a big difference between having public sex in an adult theater and fucking during the Friday showing of the next Pokemon movie. Fucking in a school playground in the middle of the city and being 30 feet off of a hiking trail in the middle of the Canadian Rockies.
Otherwise, stop yucking each other's yum. If all parties involved are doing it safely and all parties are consenting, why are you judging if I wear the top half of a horse costume and my partner is squeaking like a dolphin as they ride me? You don't see me coming in to your bedroom and judging the angle of your penetrations. But really dude, try 5 degrees more to the left, your back will thank me.
