Yes, I initially came to the site for the nudity and the sex, but I find myself taken more and more by the love. I think that is why Adriana and Daniel are my favorite couple -- something about the way they look at each other, the inflection in their voices, the smiles, suggest to me that they have a deep love for each other. So the sex is even more meaningful to watch.
But I have also come to be fascinated simply by seeing how other people live. For example, I am amazed at how central television is to so many people's lives!
