i think the biggest gripe i rly have with the "no kink in public! no pda!" people is that these issues are all them problems. like. how do i explain this. if you're uncomfortable with someone wearing an o-ring necklace in public then that is because the presence of sexuality stirs negative emotions within you. the two solutions to that are to either deal with it or to impose rules that prevent others from doing that.
the problem with imposing these rules is that there is no clear line between what is and isn't kink, what is and isn't a sex thing, and if you try to say "no sex stuff in public!" you are opening your community to the kind of scrutiny that lets authority figures decide what is and isn't a socially acceptable display of sexuality. which is how we end up with terfs and homophobes claiming that drag should be made illegal because it's a sex thing and the existence of effeminate gay men somehow threatens children.
i much prefer the solution that involves the sex-averse person just getting over it or, idk, taking responsibility for themselves. you are never going to eradicate sex from your life completely because it's a part of human existence but if it makes you that uncomfortable you can remove yourself from certain spaces, curate your online experiences, check doesthedogdie for content that you might find triggering, etc. ultimately you should be unpacking why sex offends you so much. why do you find it uncomfortable? is it jarring? maybe you've had traumatic experiences in the past that you need to work through without imposing unreasonable expectations on the people around you. maybe you're just not interested in sex, or are asexual, or find it annoying. you're allowed to find it annoying and uncomfortable and to want no part in it, but that doesn't warrant a "get sex out of my face forever!!" mentality. you don't get to harass people for whom that is an important part of their lives. the tgirl wearing a dog collar who is existing in the same room as you is not sexually assaulting you, she's just wearing a dog collar. get over it.
