Bump.
Where in America are you from? It's just that you're coming across a bit trollish. Europe is a sex paradise compared to the States but it's not exactly a little park with all the prossies lined up on demand. If you have limited time, you'll have limited travelling time, limited time for getting around large cities, and then something might crop up and she's not available. You'll find people on here most helpful, but not if it just looks a fishing trip.
Adultwork is the main UK resource. There are various other resources for other European countries. But hand holding all the possibilities for a strange request, no country and town specifics, and no background to suggest you are a genuine punter, all put together makes spending time to suggest possibilities, all the ins and out of navigating punting scenes in Europe, assuming you can get by just with English, and assuming you even have a fucking clue in the first place, you should excuse us if anyone feels it's taking the piss.
