Casual dating wouldn’t be so casual with a pregnancy complication (or an STD scare), would it?
“Expect for the worst and hope for the best” is not only not applicable to casual dating but also the worst rule when it comes to relationships in general.
Expecting for the worse will lower your standards and make you feel like you’ve hit the jackpot even when you are with the most mediocre person you could meet.
Hoping for the best will most likely break your heart harder and make you appear clingy to the average casual dater.
There is also the more established Adult Friend Finder, which is explicitly for those seeking out like-minded sexual partners.
Also in Canada, there is a new app that matches Canadians with Americans looking to escape/flee their country in case of a Donald Trump presidency! When meeting up for a casual date, especially with a person you just met online, you cannot be too trusting.
However, with this drawback comes a whole set of advantages like more options when it comes to dating styles and easier laying out of expectations for both you and the person you are dating.
