True, but their popularity and success are based on their image of being sweet innocent people. Asians in particular have double standards for their public figures. On the one hand, they have some of the raunchiest fetish type AV material, and on the other they expect their starlets to be perfectly chaste role models.

The reason someone like Gillian Chung sells is because she projects the image of pureness and innocence and true beauty. To know they are human and have sex and problems and such makes them less worship-worthy, and people like to worship their idols. It's hard to keep thinking of her as this picturesque beauty after seeing her having dirty dirty sex, and recording it too.

I don't have a problem with them having healthy sexual lives, but to allow it to be recorded makes it more voyeuristic and therefore less acceptable.
