Honestly, just go read this excellent tumblr post, I really don’t have that much to add.
If you absorb nothing else from that post, take this one thing: those people going about their day in public DID NOT CONSENT TO BEING PART OF YOUR SCENE.
I’m not saying that you can’t ever do anything the tiniest bit kinky if you’re not behind multiple locked doors, just that you need to not be a complete fucking asshole about it. It’s not doing something kinky outside of your house that’s the problem, it’s involving non-consenting people in your scene like a gross fucking creeper.
It’s really not the point of this post, but there are plenty of ways to subtly enjoy your kink in public without anyone else ever knowing about it. Think about it for a couple of seconds or google it if you need to. Here’s a hint: code words are really handy.
If you’re not willing to put any thought at all into doing kinky stuff quietly in a way no one else would notice, then can you please just fucking admit that you’re only doing stuff in public to freak out non-consenting vanilla people who are just trying to get through their days? To be clear, you’d still be an asshole if you did admit you just like freaking out the vanillas but at least you’d be an honest asshole.
And don’t start with the “oh noes ur kinkshaming!” bullshit. Kink involves consenting adults only. If you involve people without their consent, you’re just an asshole. Stop pretending you’re special and you’re tooOooOOOoo kinky to keep it to yourself, we all know the truth. Knock that shit off you tacky little brat.
While I’m at it, putting kinky picture online is fine, but for shits sake don’t tag them in a way that means people having a shitty day and looking for a little distraction can’t safely browse, say, the kitten tag (scroll through the results long enough and it’ll just make you sad). If there’s kink or nudity in your picture, tag it properly it’s not that fucking hard what the fuck is wrong with people. Non-kinky people exist and shouldn’t have kink shoved in their faces when they’re looking for cute pictures of kittens. And even kinky people like me sometimes just want to see cute pictures of kittens too, what is so fucking terrible about that?
One final point: don’t be a white person with dreadlocks. Just don’t.
