During a conversation on TV chat show "The Front Row", host Anupama Chopra asked Saif about a statement that he and his now wife Kareena Kapoor gave before marriage - about a commitment that there won't be any kissing onscreen for either of them.
Chopra asked Saif if there are any other rules as actors that the couple has imposed on each other.
He said: "No. I wouldn't even say that's in place. I don't think it's a function of being in a relationship. I have done films like 'Salaam Namaste' a long time ago. In India, it is not required in our films to have kissing scenes. I don't think it's required to be overly sexual. It doesn't suit us."
"Nobody looks comfortable doing it. And slowly, slowly reports filter through that when somebody has tried to be a little risque, that people don't seem to like it. I think the kind of cinema we have, we are a hypocritical culture.
"You can talk about things, you can see Hollywood movies, but if a kiss or a lovemaking scene is presented in a way that doesn't make you uncomfortable, it's much easier for everybody to watch," added the actor, who is the son of actress and former censor board chief Sharmila Tagore.
Saif now has strong opinions about kissing on camera.
"I would not like to kiss onscreen because I think it's not required. It's not done well enough. And there are few times onscreen that a kiss is warranted and when it is, it should be done in a way that it means everything. But our culture is about not kissing in public.
"We don't show affection in public. You're not meant to be kissing in the car. It's illegal apparently. Policewaalas will come knock on the glass, right? So I think culturally, it doesn't work. And there's no need for it," he said.
Saif was on "The Front Row" with his "Bullett Raja" director Tigmanshu Dhulia and the episode will be aired Friday.
