Once to Berlin! Am I seriously becoming an AO hitchhiker?!

Actually, I just wanted a lift!!! So I stood at the side of the road, really oldschool, and hoped that someone would drive by soon and give me a lift. From Düsseldorf to Berlin, yes, I know it's a long way! But with the crowded trains and overpriced fuel right now, I'd rather hitch a ride!!!! Then a guy stopped and let me get on the train! Did I rejoice too soon? Because somehow it all went a bit differently than I thought, when he was already making funny hints about how we could come to an agreement. He thinks I'm hot, he says. Great, and now?! Am I seriously going to get involved in a fuck in the car for hitchhiking and without a rubber?
