What do we need to know for RM research in Africa? • Who’s having anal sex? • Why, when, where, how, with who? • What’s already being done? • What have we learned? • What gaps are there? ?
Penile-anal penetrative intercourse (“Anal Sex”) Anal intercourse is a sex act where the penis is inserted into the anus of a sexual partner. The term can also include other sexual acts involving the anus, including pegging, analingus (anal–oral sex), fingering, and object insertion. Anal sex is a behaviour practiced by men, women & transgendered individuals, regardless of sexual orientation or sexual identity
Curiosity and exploration Faster ejaculation Boredom Pleasure Tighter sensation Anus is drier, more friction To please male partner Money Prestige product Anus more ‘exclusive’ Contraception Menstruation During Pregnancy Drugs and alcohol To be ‘faithful’ In the presence of vaginal STIs Part of normal sexual repertoire If you have a small penis Globalisation and pornography To get large buttocks Virginity Maintenance Intimacy Deviance [Duby, 2009, 2011] Why do people have anal sex?
Both males & females practicing anal sex are vulnerable to infection - especially the receptive partner Lack of natural lubrication in anus increases risk of rupturing membrane & blood vessels Risks of anal sex • Higher rates of infection in receptors of anal sex and higher presence of other STIs (e.g. syphilis & rectal gonorrhoea)
What we do know • Unprotected anal sex is the most efficient way to transmit HIV sexually • Condoms are less likely to be used with steady partners during anal intercourse than vaginal intercourse • Anal intercourse may account for higher proportion of HIV transmission to both men and women than commonly believed
Syndromic management STI guidelines don’t include anal STIs in routine examination Lack of communication and knowledge about non-genital STIs Providers do not inquire as to clients’ particular sexual behaviour: “sex” uniformly refers only to vaginal sex IEC/BCC materials providing safer sex information on anal/oral sex not widely available Lack of Service Provision for anal health “Have you ever discussed anal sexual practices with any of your clients, male or female?”
Anal sex taboo …you go to the clinic, the nurse will ask questions like “what was in here?” - she means in the anus. And that makes us afraid if going to the clinic… [Brown et al., 2011] Nurses (in South Africa)… especially in government hospitals, they’ve got a reputation of being really really bad, communication wise. You know they ask people “why did you do this?” if you have some type of infection ‘there’ (in the anus): they say “why did you do this?” [Respondent in Duby, 2009] • Stigma and discrimination means that anal STI sufferers do not seek/access treatment • Clinic staff not sensitised to deal appropriately with anal, rectal & oral STIs - individuals with anal/rectal STI symptoms, may not seek services they require out of fear of abuse, stigma & discrimination
So…. Misguided focus on penile-vaginal penetrative sex as primary vector for sexual transmission of HIV in Africa • Greater attention must be paid to non-vaginal sexual practices, in the light of their frequency as well as potential risks, in order to ensure a comprehensive approach to HIV prevention • Unprotected penile-anal penetrative sex, carrying the highest risk of HIV transmission sexually, needs to be addressed
