When I first moved to China in 2013 it was around 40; I subsequently lost count after a break from mongering during a long term relationship, but at some point in the last decade it definitely passed 100 (after I broke up with my now-several exes ago I went back out and played the field with a vengeance to make up for lost time). Now, I'd say approaching 200? This is over nearly 15 years however, and most of the appointments were one offs either because I'd taken advantage of travelling to sample the local mongering talent or because the service was poor and I didn't repeat. Of those dozens of women, around 20 or so will have made up 90% of my mongering, because they were the reliable regulars in that area, in that period of my life.

A good hooker is worth her weight in gold IMO; basing your numbers off how many of them you've slept with however can be a bit deceptive. In my mid-20s I had more sex in six weeks with my second serious girlfriend than I'd done with all the escorts/ONS in the preceding 3-4 years. While a major reason I've kept seeing escorts is the knowledge that for all unsatisfactory sex sessions out there, occasionally you will strike paydirt and discover one or more women in a given location who will reliably make your brains explode for cash (without the stupid song and dance routine women usually put most men through before they decide whether or not to have sex with them); but a person with a regular partner is probably having sex more often than a single mongerer (dead bedrooms aside).
