The thing that gets most people to subscribe to any voyeur site is the sex. But after watching the same couples have sex on an almost daily basis, it can become stale. So the key to get those subscribers to keep their memberships going is to keep interest in other areas that isn't just sex.
Amy mentioned Leora. She's a great artist. Most of her fan base will sit there and watch her draw and paint for hours. Layne is a highly talented musician. I haven't seen him play much since having his own apartment on VH. But Dasha and Demid's place was always one of the top apartments in RLC when he would be at their parties playing music. Alina and Eugene's apartment was great when they had those girls stay a few days. And it wasn't just because of what they did in the bedroom. They had fun drinking and dancing. They always looked like they were having a good time. It was just entertaining to watch them.
As far as Eric and Layla go, they like to play strip games. We've seen them play cards, charades, the game they played the other night with the index cards on their heads. That's what I like about them. They know how to have fun and be sexy. Plus their parties are always interesting. They haven't had a party yet that didn't end in some sort of controversy. That might be why they haven't had one in a while.
Plus I don't speak the language. And that can make it kind of fun imagining what their saying when I really have no clue. But you are right. The sex is what sells. I don't think anybody would pay if there was no sex. At the same time you have to realize these are real people living real lives. You can't just flip a switch and sex happens.
