IN THIS CHAPTER we look more specifically at issues concerning sex and sexuality. It is evident that psychoanalysis has had enormous difficulty in the area of lesbian eroticism: there are very few clinical observations and descriptions of sex involving two women, even where lesbianism is the focus of concern. Deutsch's (1933) 1 account is probably still the most extensive (see Chapter 3). Furthermore, the two main models of lesbian sexuality – as heterosexual imitation or pre-oedipal immaturity – impose great limitations on what can be envisaged. We are also aware, from various sources, of difficulties in therapeutic practice in relation to lesbian eroticism, and here we aim to address these practical and theoretical issues, and also the origins of these psychoanalytic difficulties.
