My first experience in this "hobby" was at a whore house in Kankakee, ILL 50 miles outside Chicago where I resided as a teenager in the 50's.  If I remember correctly it was $10 for an "around the world" which included rimming, bbbj and fs.  No kissing of course, it just wasn't done, and you didn't want to daty because all FS was bareback.  There were 2 cat houses in Kankakee in those days, one black and one white, girls that is, all the clients  were white, just another sign of the 50's.

 BBFS was the norm in those days and really up thru the 70's as the HIV problem did not exist and all other STD's were easily cured.  Streetwalkers in Chicago were readily available and again safe because of no hiv scare.  We heard about "call girls" but that was something exotic and costly for mysterious places like New York and Hollywood, LOL.  If you did connect with a street girl you liked you could usually get a phone no for future dates.  I always enjoyed my business trips to NY in the 70's as the line up of girls outside the Americana Hotel was like a smorgasboard of providers.

The 90's was a decade of difficulty in this hobby before the internet, we had to rely on escort agencies listed in the yellow pages, but they were a crap shoot.  The internet and cell phones have contributed greatly to this hobby.  

And yes I remember my first TV (7" B&W) my first car was a '30 chevy coupe and even in my late 70's I have ladies tell me that I'm not their oldest client.
