You then know that the sexual attraction is there, no one has led the other person on, unless you expect having sex to lead to emotional commitment, and you are not too invested in the other person should it turn out that the only thing you have in common is that you both wanted to fuck each other at the same time. Sexual attraction is not the same as love and you can have one without the other.
"Dating" is just a way to make it a bit more acceptable that we give into desire and sexual attraction.
Relationships seem a lot more fluid, they don't have the commitment to eachother and willingness to put effort into the relationship that I am used to seeing.
This has it's good points, certainly easier to get out of a bad relationship. I gave up on my first relationship after seven years, the second one still works (somewhat) after 25.
I lived in Canada for three years, UK and Australia for to respectively. I'm a Swedish-speaking Finn and we joke about Swedes much in the same way Swedes make jokes about Norwegians or Danes. We don't set out to be in a relationship just because of the relationship itself; we go for a person because we want to be with that person.
The Anglo-sphere is a totally different world from Scandinavia which itself is very homogeneous. While that is true, from what I have seen it seems they are completely less interested/invested in relationships all together.
Swedes don't "date" the way you guys do, so you're kinda spot on with you analysis.
