The often NSFW icons include anatomically accurate genitalia, whips, chains, fuzzy handcuffs, and even some sexually-suggestive fruit. There are also special, specific collections like BDSMS, Snow Bunny (holiday appropriate), and Safe Sext.
Katy McCarthy, one of the creators of Flirtmoji, discussed the project in an interview in November:
Some of these, like the vulva in particular, are really detailed and surprisingly anatomically correct. Did you have to think about ways to also make them sexy?
Well that’s the meat of the project. That’s where some of the most heated debate came out. To pass our test, the drawings have to be sex-positive. Anyone has to be able to look at them and not feel offended. There’s definitely a ton that didn’t make the cut.
But some people will probably find these offensive anyway.
Well sex-positive and offensive… there’s definitely a judgment call on that. There are people who will be very deeply offended — people who are offended by certain sexualities — but we’re not worried about those people. I mean, get your shit together. People are having sex, and it looks like this. And yes, part of being inclusive is that it’s all sexy. Even if it’s not my thing, necessarily, I wanted the Flirtmoji to be sexy because it’s someone else’s thing and it’s sexy to them.
