Women's Anal Sex Practices: Implications for Formulation and Promotion of a Rectal Microbicide

Abstract - AIDS Education and Prevention, April 2008

To gain insight into practices that may inform formulation and use of rectal microbicides, in-depth interviews were conducted with an ethnically diverse sample of 28 women who engage in anal intercourse. Microbicides are compounds under development to decrease sexually transmitted infections. Most women practiced anal sex in conjunction with vaginal intercourse. Anal sex typically was not preplanned, and few women reported preparation. Condom use was rare. Most women relied on saliva, vaginal fluids, prelubricated condoms, or used no lubrication at last intercourse. Women were uncertain about the amount of lubricant used during sex, with typical estimates of 1 to 2 teaspoons. This may prove challenging to the formulation and promotion of rectal microbicides, as substantially higher amounts may be required. Additional challenges include infrequent use of packaged lubricants, and typical male lubricant application, which may make women's control of rectal microbicides more difficult. Women overwhelmingly expressed interest in rectal microbicides.
