I get that people that are really into anal play do a lot of prep to make the ass safer and more appealing. I get that safe ass eating is a thing and takes some prep.
But that also means it’s a highly specific sexual act that takes a lot of prep, conversations, and assurances of consent. Ass eating isn’t something you do unless you’re in a committed relationship with a fair amount of trust.
The authors of ass eating memes aren’t taking in this context. Instead, the meme is more like “man, I’d like to eat that random person’s ass out of nowhere without any prompting”. And what I’m saying is that 9 times out of 10, that person’s ass is fucking nasty at that moment.
Now if they wanted to do it right, it would be more like, " man I’d love to date that woman for a while, fool around a bit, bring up the idea of ass eating, buy some dental dams, wait for her to douche and clean her asshole thoroughly, and then go to town on that specific hole". But that’s not what they’re doing.
