Indians have more respect and most reserved than the westerners. I think   lot more thought has to go there in the movie for such a scene. In normal love scene, it will be ok. But in front of choreography, lyrics, costume etc, this may be more artful.

Tamil and Hindi Actress Ghajini fame "Asin" in her recent interview to the press said that she wont mind in doing kiss scene or wearing bikini if story demands.

This is the current situation in the film industry. Kissing lip to lip has become normal and even censor does'nt bother about these scenes. As it is common nowadays for the younger people who are performing these things in their colleges.

I have published here some lip to lip kiss scene from movie stills where the actress are nor emotional than the actors.

In Tamil movie kamal hassan is the specialist and best performer for on screen kiss scenes.
