Ethnographic research among Glasgow female prostitutes working in stre
et, sauna, pat, escort agency and 'sugar daddy' sectors investigated p
rostitutes' accounts of the occasions in which condoms were not used f
or penetrative sexual encounters. Such occasions were a minority of co
mmercial sex encounters and a majority of private sex encounters. Alth
ough prostitutes saw condom use as inappropriate in private sexual rel
ationships this was not, as has been suggested, an aid to relationship
interpretation as either private or commercial. Condoms in commercial
sex were seen as routine tools of the trade, and hence emerged as emb
lems of prostitution. These emblematic qualities were found in turn to
produce both challenges to condom use fr om customers and opportuniti
es for prostitutes to manipulate customer relations by judicious suspe
nsion of condom application. Both norms of gendered role-play and pros
titute status were highlighted as threatening condom use in some situa
tions, while prostitute status could also be used as the basis of rati
onal argument for condom use in others. Relational issues such as fami
liarity or a desire to communicate trust were at the forefront in expl
anations of condom non-use. Perceptions of physical power and the auth
ority to permit or withhold sexual service or Profit were determining
influences crucial in condom use negotiation.
