Nous avons pris la «partie de sexe intense» pour cadre analytique de comportements spécifiques et fréquents parmi une petite minorité d'hommes gays à Sydney, en Australie. It emphasises the importance of ‘intensity’ in order to understand better the relations between sex, drug use, pleasure, care and risk in some gay men's lives. Intensive sex partying describes this coincidence of factors and locates them in relation to the multiple pleasures offered by sex partying. Sex partying occurs on multiple sites (domestic spaces within dance parties sex parties sex-on-premises venues) and appears to be geared to the maximisation of sexual pleasure. The men appear to be involved in both high-risk, adventurous sex practices and a specific form of partying distinguishable from dance partying and ‘clubbing’. These occur at a contextual intersection between a sub-group of sexually adventurous gay men and ‘party boys’. The behaviours included a higher frequency of dance party attendance, more frequent sex, more anal sex, multiple sex partners, more unprotected anal intercourse with casual partners and more frequent drug taking. Intensive sex partying is a framework developed to analyse specific frequent behaviours amongst a small minority of gay men in Sydney, Australia.
