The range of variation in the female far exceeds the range of variation in the male.

Few males achieve any real freedom in their sexual relations even with their wives. Few males realise how badly inhibited they are on these matters.

Cheese crumbs spread before a pair of copulating rats will distract the female but not the male.

The history of medicine proves that in so far as man seeks to know himself and face his whole nature, he has become free from bewildered fear, despondent shame, or arrant hypocrisy. As long as sex is dealt with in the current confusion of ignorance and sophistication, denial and indulgence, suppression and stimulation, punishment and exploitation, secrecy and display, it will be associated with a duplicity and indecency that lead neither to intellectual honesty nor human dignity.

If all persons with any trace of homosexual history, or those who were predominantly homosexual, were eliminated from the population today, there is no reason for believing that the incidence of the homosexual in the next generation would be materially reduced. The homosexual has been a significant part of human sexual activity since the dawn of history, primarily because it is an expression of capacities that are basic in the human animal.

Males do not represent two discrete populations, heterosexual and homosexual. The world is not to be divided into sheeps and goats. Not all things are black nor all things white. It is a fundamental of taxonomy that nature rarely deals with discrete categories. Only the human mind invents categories and tries to force facts into separated pigeon-holes. The living world is a continuum in each and every one of its aspects. The sooner we learn this concerning human sexual behavior, the sooner we shall reach a sound understanding of the realities of sex.

It is amazing to observe how many psychologists and psychiatrists have accepted this sort of propaganda, and have come to believe that homosexual males and females are discretely different from persons who respond to natural stimuli. Instead of using these terms as substantives which stand for persons, or even as adjectives to describe persons, they may better be used to describe the nature of the overt sexual relations, or of the stimuli to which an individual erotically responds.
