It's time to get yourself a screenrecorder, there are lots of them, and you can find them here on this forum.
A lot of members discribed them and gave tips, it is some work to find them in the threads.
In my opinion they are all boring to watch, they all have theire own routines (and so do we) a few of the couples like sex a lot , the others are regular couples, and about the "sexcouples"thats boring to watch either, at least, if you're not a tennant. My lack of knowledge of the English language keep me from express myself clear therefore I stop to write more about this subject.
Whatever it is called, and whatever the reason, I enjoy it.
Maybe you're right about theire emptyness (how we see it) , however, for them it might be a good life I don't judge them, they seem to have fun.
