Whoa! I like to use the word 'escorts,' or 'call girls,' or after a drink or two, maybe 'party girls.' I find the word 'prostitute' so...judgmental. ;-)
I think my point was -- back in the day it was more accepted. Today there's a stigma attached to using escorts. Old guys I've met still talk fondly of going to Pauline's (is that the right name?) over in west 50s during the the 1940s in groups of a half dozen or more.
