Speak for yourself. I don't particularly care to see "affection" nor just to see sex. I like to see different interactions with different people. Both apartments have fallen into a stalemate because there's nothing exciting or different to see in any of them. And I would argue that Charlie moving into Tver is in part what hurt that apartment because Akira now isn't free to do shit with any new girls that come on and watching the two of them got boring real quick. Watching Sonia Ivo and Petra got boring real quick. And no matter how much sex Messa and Christy have and don't have, the two of them will get boring like the rest of them.
I'd also disagree about Messa not liking sex. He obviously likes it to a significant extent otherwise Christy would have never be able to fuck him behind Nastya's back. And look at how much fun he had there with Phil. I still think that he doesn't like the idea of being tied down to just one girl. When he came into the house, it was just Phil and Dizi. Now Phil's gone and he's in the house by himself with Christy.
