The two basic most powerful instincts of all forms of life are self-preservation and reproduction. We are all well aware of the intense and all-powerful urge for life. Man will undergo any suffering or sacrifice in order to continue to live. Even the very old and feeble  hold on to life desperately. The other instinct, the instinct of reproduction, is not always so frankly and honestly acknowledged. The belief in sex as a mysterious, dynamic and all-pervading force of life has its protagonists as well as opponents. Some deny or denounce it completely. Some religious, cultures and self styled "moralists' have tried to belittle sex and make men and women feel ashamed about teh sexual side of life. In modern India, for example, the word sex is not considered a respectable word and is not mentioned in plite society. Any display, mention or reference to sex in mixed company is considered vulgar and is frowned upon.

From a strictly biological point of view sexual intercourse is nature's method for the continuance of life. It is necessary in life is to continue. Sexual reporduction is an advanced step in the evolutionary scale. The simplest forms of life reproduce through the fission method, where the object grows and divides itself into two and continues to multiply endlessly in this manner. Without the sexual act all forms of higher life could not be reproduced and would abruptly come to an end. To ensure reproduction nature has made sexual intercourse the most exciting and pleasurable experience of life.

Sexual Instinct Dominates Life :

The influence, dominance and constant pressure of the sexual instinct on our daily life is all-pervading. Man's preoccupation with woman is almost total. All advertising and display designed to attract attention chiefly employ the female figure for appeal. We are constantly aware and responsive to the opposite sex. The greatest single determining factor in human life is sex. Our actions from infancy to old age are dominated and motivated by it. Those who attempt to ignore teh sexual side of life when dealing with the subject of life as a whole cannot be honest. It would be an attempt to bypass the most vital force affecting and influencing life, simply because it is a difficult and delicate subject. Sex is not only the most  initimate and vital aspect of human life, it can be equated with life itself. Sex is the source of life.

Sexual attraction is the healthy urge which a member of one sex feels for a normal, healthy member of the opposite sex. The act of reproduction can take place between any two normal members of the opposite sex. Nature has done a perfect job in making the sexes alive, aware and ever conscious of each other. The magic of the sexes is strong, exciting and irresistible. There is no bliss greater than the all-powerful union between man and woman. There is no pleasure so eagerly sought after by man as union with a beautiful, loving woman.
