Gyllenhaal appeared totally nude in the 2003 black comedy, but insists that she would only do it again if it is totally necessary.
"After Secretary, people knew that I'd get naked, but I won't get naked for anything - only if it makes sense," she told Tatler.
The actress, 30, also claimed that fiancé Pete Sarsgaard does not get jealous when she films raunchy scenes on camera.
She said: "I hate it when Peter does a love scene. He's very understanding - it doesn't seem to bother him [when I do one].
"I'd hate it [if he was doing it]. I'd put up with it, I'd understand, but I wouldn't like it."
