What is casual dating?
Unlike many people, casual dating is not always about sex. Sometimes it does. In some cases, people are looking for "friends with benefits" who also go out and eat or get some drinks. For others, casual dating means they go out with someone who interests them without any real motive to take things to the "next step", as often happens in traditional relationships.
It is simply about ensuring that you keep your options open. That means you are playing on the pitch to find out what you want. Maybe casual dating is the only thing you want. There is nothing wrong with that.
