In a way it's hard for me to imagine such a thing, (specially no sex thoughts .... western scientist made a statistic that men think about sex every 7 seconds) but I've been to something similar in the army.
What happens if you can't make it? What about health issues(pregnant women)?
sex like gattuso 8 said is something natural and unavoidable but it is much more common in the west imo, sex there is everywhere, back home i tend to think much less about it because i am busy with other things to do.
as for pregnancy and illnesses, you are strongly suggested not to fast, and for people who are traveling they are allowed not to fast although that does not really imply to todays world where you can travel halfway across the world in a few hours. there are many exemptions to fasting its not a method of torture its actually a good practice, gives some new challenge to your life instead of following the same old routine and it makes a big difference for the poor since islam is a religion of equality where social status, skin color, ethnicity, wealth ..etc make no difference between its followers.
