This relative sexual conservatism extended into her AV career. The sex scenes in all but her final video were simulated. Even at the end of her AV career, Kobayashi's attitude towards sex remained modest. Interviewed at the time of her retirement, Kobayashi said, "I love sex. But, just because I'm an AV actress, it doesn't mean I'm brim-filled with experience. I've done orgy movies, and lesbian scenes and loads of abnormal stuff, but the world of videos isn't a real world. My normal life is really plain. I couldn't imagine having sex anywhere other than in bed and taking part in an orgy would be unthinkable. I'm happy enough with just the missionary position."
