Theories of sex
Three Essays on the Theory of Sexuality German : Drei Abhandlungen zur Sexualtheorie , sometimes titled Three Contributions to the Theory of Sex , is a work by Sigmund Freud , the founder of psychoanalysis , in which the author advances his theory of sexuality , in particular its relation to childhood. Freud's book covered three main areas: sexual perversions ; childhood sexuality; and puberty. Freud began his first essay, on "The Sexual Aberrations", by distinguishing between the sexual object and the sexual aim — noting that deviations from the norm could occur with respect to both. Discussing the choice of children and animals as sex objects — pedophilia and bestiality — he notes that most people would prefer to limit these perversions to the insane "on aesthetic grounds" but that they exist in normal people also. He also explores deviations of sexual aims, as in the tendency to linger over preparatory sexual aspects such as looking and touching. Turning to neurotics, Freud emphasised that "in them tendencies to every kind of perversion can be shown to exist as unconscious forces

It is widely known that there exists a multitude of possible explanations for the maintenance of sex; however, it is less clear how to handle such an explanatory pluralism. In this paper, we address one older and one more recent discussion on what might constitute a good theory for sex and find that they reflect a trade-off between maximizing the scientific virtues of generalism, realism, and precision. A historical analysis indicates that varying research interests and research backgrounds of the different biologists shape the trade-off. We use the reflection on the trade-offs in order to understand the existence of the diversity of theories in the field and discuss how to address the explanatory pluralism. We find that the existence of multiple theories for sex, that is, explanatory pluralism, is not surprising or embarrassing but can be seen as a resource. Still, it is important to clarify the possibilities of integration of different theories.

We can examine issues of gender, sex, sexual orientation, and sexuality through the three major sociological perspectives: functionalism, conflict theory, and symbolic interactionism. How does feminist theory address both both micro and macrosociological approaches? Read on to learn more.
At the turn of the twentieth century, biologists such as Oscar Riddle, Thomas Hunt Morgan, Frank Lillie, and Richard Goldschmidt all puzzled over the question of sexual difference, the distinction between male and female. They all offered competing explanations for the biological cause of this difference, and engaged in a fierce debate over the primacy of their respective theories. Riddle propounded a metabolic theory of sex dating from the late-nineteenth century suggesting that metabolism lay at the heart of sexual difference. Thomas Hunt Morgan insisted on the priority of chromosomes, Frank Lillie emphasized the importance of hormones, while Richard Goldschmidt supported a mixed model involving both chromosomes and hormones. In this paper, I will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic theory of sex.
