Small World Day II

1)What is the reasoning for the emphasis on sex?
There are two particular parts in this book that emphasize sex. The one section involves one of the woman not being able to sleep. She then talks about using his vibrator, which seems out of the ordinary for the text and it was not something I saw coming. She also makes jokes about how the battery would die before she finshed, just like a man. She writes this down in her journal. Next, another man wants to join the mile high club. This is more like a party joke then anything else, but he really wants to. I wonder what all of this has to do with the book. What it means? Is sexual pleasure part of this journey?
2) What is it with time zones?
The second part of this book begins with people throughout different time zones. This is very much related to a journey. People have different travels, at different times in the world. but in reality, they might be having similar experiences at different places. In life, it doesn't actually matter what the time is, but what the experience is. Lodge is insinuating this a little.
