Aquarius: Honestly, this sign is too lazy to cheat. They aren’t going to go through the trouble of swiping through dating sites and hiding text messages and sneaking out to meet up with someone else. Keeping up with one relationship is enough for them.
This sign doesn’t want to be stuck doing all the work. It’s tiring. It hurts their jaw. It gets boring. They would rather have sex than get stuck going down on someone for too long, so they try to avoid giving oral whenever possible.
