>>938079653I spent 2012-2019 in Shanghai. They start them in the brothels at 14, but they always have I.D. that says they're 20. However, that is not the kind of thing the cops ask about during the regular busts when the VIPs come to visit, oddly enough.
I once saw a whore working the popular place on Nanjing Road with the hook that you could do anything to her toddler daughter except vaginal (and presumably decent oral; I didn't ask.) Anal was absolutely on the menu while she held her, I could hear her saying 30 feet away.
I stopped paying for sex after hearing that, and settled down with a 25 year old upwardly mobile professional with a rape fetish.
