You have a reasonable expectation that nobody but your second floor neighbors can watch you. That difference is important. You know your neighbors. And even if you don't know for sure that they won't stand at their window and masturbate to you lying next to your pool, it's fairly unlikely due to you easily being able to identify them and throw the book at them.
It's a bit different with random strangers walking by your property. Not only does it multiply the chance of getting a pervert, they are also fairly sure they can get away with perving on you if you don't happen to know them.
