I can't remember if the show has always been like it - I don't know if I'm romanticising the past of BB but I'm sure they used to blur out nudity? Or cut to other cameras whilst running the audio of an intimate scene.
There's something hyper-sexual about current reality TV that just doesn't interest me... and I don't think you have to be prudish, asexual or "old" to be put off by it. It's just...not entertaining. It doesn't enhance the show, it doesn't get people talking beyond "omg did u see marnie's tits", and it rarely even excites me in a shallow way
