Hey, so I'm taking a trip to Switzerland July 20-30, and I need a little help on making it the least awkward trip possible. We're flying into Zurich, then driving to a place called Lucerne, then either taking a train or driving up to Germany for a day, but we will mostly stay in and around Lucerne. I come from an extremely conservative family (meaning religious and nonsexual, not in a political sense), and I know Europe has a lot of nudity in it...so what can I do to make it not very awkward? Are there billboards with naked women on them? I already know not to channel surf (learned that the hard way in Greece), or really even to turn the TV on. Is pot widespread? How much other sexual stuff is there? Thanks.
