Great thread indeed.
I think environment is definitely a factor here too. I studied in a town (not Danmark) where you would always share a house with at least a couple of other people. So you really had no privacy.
And then- many moons ago- there was no Internet dating!! So you had to actually go and physically approach somebody. Which demands a lot of confidence and at the same time gives away that you're really interested.
Anyway, sometimes it seems good information comes along when you don't really need it anymore.
But if you want to get yourself psyched up for dating, maybe this will help. It's a hypnosis CD by a qualified hypnotherapist from Las Vegas:
