I think Holland is pretty liberated. Whenever I take friends from other countries through the red light district here in Amsterdam, they are amazed that this is even possible. A cute girl that I'm working with now for a school project told me casually that I should go and see a live peepshow in the red light district when my ex from Sweden came, because it's 'fun'. What it was was seeing two people fucking about 1 meter away from you, on a bed that rotates so you can view it from every angle in your little booth. I don't know how this is in other countries (like the US?), but you can discuss sex pretty easily with Dutch girls in my experience, although this obviously depends on the girl as well.
Oh, and Swedish girls are horny creatures too.
I heard that Swedish girls will have more one night stands, without expecting any kind of commitment or whatever. I was at a new year's party in Sweden, and at one point I came back into the living room of the house and it was only girls, perhaps 10 of them (some of them HOT) and they were playing that "Never have I ever..." drinking game, telling eachother the naughtiest things they had done, and obviously enjoying it. I've read that Swedish girls are also the most bisexual girls in the world. And did I mention they are hot? Wait, what were we talking about?
edit: A friend of mine had his birthday party in a bar last night in Amsterdam. Around 3 AM he walked back to his home alone, drunk, and this girl passes him on her bike. They make eye contact and she stops her bike and sits down in front of it (she had also clearly been drinking). So now she's sitting on the street as he walks up to her. She says something along the lines of "You have to help me" or "Can you help me?". He basically responded confused and as he was close to her, she opened his pants and she started giving him a blowjob right then and there, without any further conversation, until he came.
I was reminded of this thread when I heard the story. Although I've never heard of anything close to this ever happening before.
