Police are pushing for cóndoms to be banned from Edinburgh's licensed saunas.
The move comes as the city council weighs up whether to grant licenses for five saunas in the Scottish capital.
Police Scotland argues the authority should only grant licenses if items of a séxual nature are prohibited on the premises.
However, the séx workers' charity Scot-pep says the police's proposal could lead to an HIV epidemic.
A council decision on new licence rules could end Edinburgh's more tolerant attitude to the séx trade.
Campaigners say that any ban on cóndoms would result in unprotected séx and higher rates of HIV and other séxually transmitted infections.
Earlier this year, six other saunas had their licences suspended following raids across Edinburgh.
