Oro-anal sexual practice among female sex workers in Melbourne: implication for extragenital gonorrhoea and chlamydia transmission.

UNLABELLED: Background The prevalence of sexually transmissible infections has been low among female sex workers (FSWs) in Melbourne, Australia. However, the prevalence of gonorrhoea and chlamydia, especially at extragenital sites, has increased since the mid-2010s. Oro-anal sex (i.e. rimming) has been identified as a risk factor for extragenital gonorrhoea and chlamydia. However, rimming has rarely been studied among the FSW population. The aim of this study was to examine the proportion of FSWs who had had rimming with their male clients.

METHODS

A cross-sectional survey among FSWs attending the Melbourne Sexual Health Centre in Australia in March 2018 was conducted. All females aged ≥18 years and self-reported as a sex worker were eligible. The survey included questions related to the number of insertive and receptive rimming partners with their male clients in an average working week.

RESULTS

Forty-five FSWs completed the survey; five (11.1%; 95% CI: 3.7-24.1%) FSWs had had insertive rimming and 19 (42.2%; 95% CI: 27.7-57.8%) had had receptive rimming with their male clients in an average working week. The median number of insertive rimming partners was two (interquartile range (IQR) 1-5) and the median number of receptive rimming partners was one (IQR 1-3).

CONCLUSION

Insertive rimming is more commonly practiced than receptive rimming among FSWs with their male clients in an average working week.
