I do believe that John of Japan's very first post to you was an excellent answer to your initial question. In short, yes, sometimes a missionary will become tempted and fall due to the heathen culture around him.....is this not the same thing that happens in America far too often? However, the same steps that we take here in the States to keep ourselves from temptation are the same ones we will use on the mission field.
You might say, "Well, the women here in America don't have a culture of walking around nekkid". Have you been to the mall lately? Or any beach in any of the coastal states? Much of the time the attire in America may as well be gone altogether for all it hides.....and preachers here have to deal with seeing it walk into their services all the time. What do they do? How do we here keep our families safe? We try to minimize the impact, give them instruction and training, and yes, AVOID the places where we KNOW these sorts of things will be more prevalent.
