I disagree with you entirely. I don't have any stats on this, but I am going on simple math. There is a HUGE difference between the average promiscuous woman and a sex worker. I can see an average woman hooking up a few times a week when she is young. Even on the extreme end and she hooks up every day, that's 7 times a week, it doesn't compare to 7-8 times a day, 6 to 7 days out of the week for a sex worker. Even on a bad day, a sex worker at an AMP probably gets at least 3-4 customers. Just to clarify, I am referring to FS spots, not rub and tug places. On the low end, 4x6 is 24 exposures a week vs 7 exposures for an average chic. That is more than a 3:1 ratio of exposure for the AMP lady. On the extreme end, 7x7 is 49 exposures a week vs 7 exposures for an average chic. Now the ratio explodes to 7:1. And we all know that finding a chic that sees sleeping around as a hobby is a unicorn in itself, so I would put ratio of exposure at a much higher number such as 7:>1.
I agree they are regular people at the end of the day and when they leave the hobby they lead normal lives, but you cannot ignore that fact that they have a much higher chance of exposure to catching something than a woman that sleeps around on a weekly basis. Again, this is my math not specific stats so don't get your undies all bunched up.
