Plans to eliminate the so-called "contact ads" appear to be on a kind of permanent hold, partly justified by the precarious economic state of Spain's print media.
However, the underbelly of a trade which is legal in Spain but not recognised as an actual job is far from pleasant, with human trafficking constantly rearing its ugly head.
"Clients don't realise that many of these women could be victims of trafficking.
Lots of people would be more wary if the prostitutes were clearly under lock and key or had obviously been subject to physical abuse.
Among the young men of the Spanish provinces, even in the late 1980s, sleeping with a prostitute was no longer something you did as way of losing your virginity: it could actually be seen as cool.
In the 1990s, magazines such as Interviú, which prides itself on its investigative journalism, would think nothing of publishing "erotic guides to Spain".
They don't realise that all it takes is a death threat to their families back in Nigeria or Brazil, and the woman is already being coerced into prostitution." The laws in Spain are of little help either, with prostitution currently a permitted activity – but with no labour rights.
"They're already frequently leading a double life or are considered social outcasts and often are in dire need of money," said a Spanish Red Cross social worker running a healthcare programme for prostitutes.
"Economically the women I'm dealing with are at the end of their tether, and the lack of other employment possibilities makes everybody more nervous about keeping clients. They'll be more willing to accept it when a client doesn't want to use a condom, for example, to be sure they get him to sleep with them." When prostitution and trafficking overlap, the legal situation grows even more discouraging.
Historically it has long been seen as an expression of individual freedom – first as a pressure valve for the strait-laced family-focused environment of the Franco years (when prostitution was quietly ignored), and then consolidating itself after the dictator died.
Then, as now, brothels would be listed in the yellow pages, albeit under the coy title of "nightclubs", and nobody batted an eyelid.
Cut to a Saturday night inside the said Don Jose "club" – three storeys high, flashing neon lights, two bars, a VIP zone and some 70 sex workers, clad in everything from nightgowns to G-strings to the very briefest of shorts – and, according to local regulars, business is booming.
"The place is heaving every weekend," comments "Alvaro", an experienced brothel-goer in his late forties.
