Some propositions on male and female sexual orientation will be considered. Some of these are established; others are more speculative. The aim is to offer some notes towards a coherent, comprehensive theory of sexual orientation. 1. ⋯ The active males contain a substantial proportion of self-identified bisexuals; and the active females a substantial proportion of self-identified butches. 8. These two active categories (butch lesbians and male bisexuals) share a number of endocrinological, psychological, morphological and behavioural features vis-a-vis their exclusively homosexual and heterosexual peers. Methods of testing some of these ideas are presented.
