Germans Don't Date

A few days ago, miss Paula Varjack--ever with her finger to the pulse of pop culture-- sent me this:

Part 2 Part 3 Part 4
And it got me thinking about the subject of German dating. To be honest, I've never seen two Germans on a date together. All the couples I see out in public have obviously been together for a while.
So I asked Brian's roommate Jahn about this and he says, "No, no we don't date."
"But you have sex, right?" I asked as a follow up.
"Yes."
"But then how do people wind up in relationships?"
"Well maybe you have sex a few times and then if you like someone you go out for a date."
I was stunned.
So then I asked my friend Mella about this and she confirmed it.
"No, you have sex first. That's how I met my last boyfriend. We had sex and then after we were having sex for a while we decided to start dating."
I was aghast.
"It's not like that in the states?" She asked.
"No," and then I proceeded to explain to her about how in the states you go on a date and the guy buys you dinner. You're not expected to put out AND you get free dinner. Then after 4 or 5 dinners, you maybe sleep with him.
"Really?" She asks.
"Yeah, of course. Although sometimes instead of just dinner you go to the movies or to clubs or something. Some guys don't pay for you but many still do."
"That sounds great!" She says. "I'm moving to America!"
