you are lying, firstly, it is not efficient for a chinese prostite to wash her vagina every visit, that would cause a nasty dry rash. the correct method is to have a low sink and when the customer arrives he spends the first 5 minutes cleaning his penis under your strict watch. the real issue with being a whore is sweating, you sometimes have fun and get into the action and then your make-up falls off and men don't wanna fuck a crypt-keeper granny born in the 90s.
once I called a chinese woman who hit on me "jie jie" and she cried, I played it off as saying she was just smarter and more emotionally mature than me, not out-dated. lol.
