The Gigolo 2 (2016) on Netflix

Hong Kong sex comedy The Gigolo returns with a darker and even more salacious sequel, again starring Dominic Ho as the gigolo king who can send any woman to seventh heaven with his top-notch skills and attention. Since working his way to the top of the trade in the last film, Feng is now a club owner with a booming business and disciples of his own. Naive C-list actress Monica (Connie Man) follows her friend into prostitution in order to earn money for her mother's surgery. However, her shy and frigid performance in bed turns off the disgustingly rich and sex-crazed clients she services. Determined to improve, Monica seeks Feng's help to learn the tricks of the trade.
