So I have a feeling that if this agency and its ilk had existed then, it would have been stuffed to the gills with male members (oo-er) and a very few independently wealthy women looking for a bit of fun. All of which means that it would have failed ... or quickly become a kind of gay dating service.
Fascinating stuff. Oh, and the reason I've pixellated the name of the agency is not because of moral outrage ... it's because I'll be damned if I'll give advertising space to spammers. You want to find the site? It wouldn't take long on Google.
The question you have to ask yourself is ... why would you want to find it?
