In 30 years you must have met some real munters as well, I certainly have and I know that NIK has also suffered some disasters, it's all in his book.
Of course they haven't all been gorgeous over 30 years. In the bad old days you went up into a walk-up and all you knew for sure was that there was a prostitute in the room. However, we're all different - I can see that facial attractiveness is very important to you (you insist, fair enough, on face pix), but attitude, service and, of course, hygiene are all more important to me.
Each to their own, but I would rather have a fantastic BJ from an average-looking girl, that a disinterested one from a stunner.
There used to be a Scottish prostitute in Peter St, years ago, who wasn't attractive and wasn't young, but in the age of universal covered oral in Soho, she would do you a really great OWO to completion, and I went time and again. And, yes, closed my eyes.
I really do wonder if those punters who have started since the internet and never walked into a Soho/Shepherd Mkt walk-up or got an address off a newsagent's window postcard realise how much the sex trade has changed, and how lucky they are to have resources that we couldn't have even imagined back in the day.
