We live in a fast-paced world, so we have to multitask a lot and speed up all sorts of processes. It's all about efficiency. Sexting made flirtation and dirty talk very efficient – emojis make it even easier. Straight up, this is a post solely devoted to sexting using nothing more than your fierce emoji game. It gets a little crude, but I don't think anything is technically NSFW.
This is as simple as it gets, plus it's pretty straightforward, so hopefully you don't have to worry about the recipient completely misunderstanding you.
