Singaporean female sex guru Lee Hui Zhen was approached by some of her male clients for sexual services, reported Sin Chew Daily. Lee, 33, was quoted as saying that some of her customers did not think she could be a sexologist without being involved in sexual intercourse with them. “I have always stated clearly to my clients that there will be no touching and they do not have to be naked during consultation. “However, there are still a number of clients asking for ‘special’ service,” she said.
