Normally People sufferring from inferiority complex or ignored indulge in all such activities.Men and women both have significant role to play in nature. Child born first develops love with mother only, on attaining maturity, again with a female only. Their importance cannot be reduced. Logically otherwise I am still to find a female more beautiful comparing to male in any living body except humans viz. dog, horse, lion,birds, snake, etc.,etc., are more attractive comparing to their counter part femals.If anyone knows exception, please let me know.
