The safe thing is probably not to use movie quotes during sex.
"It is a strange fate that we should suffer so much fear and doubt over so small a thing. Such a little thing. "
“All right. We’ll put it away. We’ll keep it hidden, we’ll never speak of it again. No one knows it’s here, do they?”

“This is going to feel a bit weird”
“Are you not entertained?” and “Am I not merciful?”
Both from Gladiator.
I know, Iknow. Neither is nearly as good as many of the ones already nominated. But when that movie came out, I remember being told by a colleague at a dinner party that her husband (who was a huge Gladiator fan) had actually recently been insisting that she call him “Maximus” in bed, and that while he was in this phase, the two of them actually did have to say these lines to each other during sex.
Compared to some of the crazy stuff I’ve heard of people doing in terms of sex-games/role-playing etc., this actually strikes me as being quite tame. But it is the kind of thing that’s difficult to keep from crossing your mind and making you smile to yourself a bit when you see the guy at the next dinner party.
