coz tihs is the first step towards early sexual relationship it is really difficult for us human beings to resist if we are kissing our luvs.It can be proved very easily u just ask the one who has gone thru early sex he or shall will tell u that the start was from the kiss.
More over our country is culturely rich we should not erase the things for which we are known in the world.we shd. not copy western culture blindly.Western culture is rich in other good things also like science n tech, helping , caring for the society.We shd copy/learn such thing from them instead of nudity, vulgarity, loudness in music.
i think we should not forget our culture and instead of copying western culture we shd spread our own culture.
