The superstar says he was "forced" to kiss this time, and says it was only a demand of the script."I had a couple of rules actually - that I won`t ride a horse and I won`t kiss. Both are cumbersome. I don`t know how to do both on screen," Shah Rukh said at a media summit here Friday.Ever since the release of Yash Chopra`s directorial JTHJ Tuesday, social networking platforms have been abuzz about the kiss scene between Shah Rukh and Katrina Kaif. So, moderator Vir Sanghvi, on behalf of Twitterati, asked SRK: How come he kissed this time!"I will be very honest. Adi (Aditya Chopra), Yash ji and Katrina, and I say this with all humility and thankfulness to them, that they knew I was awkward, I had issues and I am a very easy actor to work with. They are like my family and they said, `You don`t have to do this` and then they got together and they forced me and then even paid me for it.""So... when heroines say that `I wore a bikini because the story demanded me to`, I did it (the kiss) because the story demanded it. Believe me or don`t believe it," said the 47-year-old actor, who has been in showbiz for over two decades.Shah Rukh feels doing something as intimate as a kiss on screen, is mechanical."It is very mechanical with 100 people telling you what to do. It`s very odd. I don`t even do photoshoots with heroines if it is not for my film and that is also rude, but I don`t want to waste anyone`s time. I find it very awkward taking my shirt off and posing. I can do it in character for film," he said.But JTHJ was "extremely special because of Yash ji"."He spoke to everyone and he said `Shah Rukh, this is a requirement`," recollected Shah Rukh.The actor was extremely close to the late filmmaker, who breathed his last Oct 21 following dengue and subsequent multi-organ failure.
