In this extract Jeffrey Weeks is writing about the paradox that, as sociologists, we have become increasingly aware of the culturally dependent nature of human sexualities, whilst, at the same time, the claiming of certainty about our sexuality has become increasingly important to us as individuals: The very idea of a sexual identity is an ambiguous one. For many in the modern world – especially the sexually marginal – it is an absolutely fundamental concept, offering a sense of personal unity, social location, and even at times a political commitment. Not many, perhaps, say ‘I am heterosexual’ because it is the taken-for-granted norm, the great unsaid of our sexual culture. But to say ‘I am gay’, ‘I am lesbian’, or even ‘I am a paedophile … or sado-masochist’ is to make a statement about belonging and about a specific stance in relationship to the dominant sexual codes. It is also to privilege sexual identity over other identities, to say in effect that how we see ourselves sexually is more important than class, or racial, or professional loyalties. As the song puts it: ‘I am what I am, my own special creation’ and in saying that we are ostensibly speaking of our true essence of being, our real selves. Yet, at the same time, we now know from a proliferating literature that such identities are historically and culturally specific, that they are selected from a host of possible social identities, that they are not necessary attributes of particular sex drives or desires, and that they are not, in fact, essential – that is naturally pre-given – aspects of our personality. … So there is a real paradox at the heart of the question of sexual identity. We are increasingly aware, theoretically, historically, even politically, that ‘sexuality’ is about flux and change, that what we so readily deem as ‘sexual’ is as much a product of language and culture as of ‘nature’. Yet we constantly strive to fix it, stabilize it, say who we are by telling of our sex.
