Psychologist Dr Ng Man-lun
Dr. Ng Man-lun, a renowned psychologist specializing in sexuality, tells us why sex is power and why monogamy hurts.

Filling the void is one of my principles.
I was in medical school and there were only a few psychiatrists. So I chose psychiatry as my specialization.
The word “sex” captures all attention. That’s how powerful sex is.
I show up in newspapers and magazines more than other medical specialists, and the reason is simple – I talk about sex.
Theories work like chains – they supplement each other and no single one is perfect. Even Newton’s theory of gravity is not perfect. You drop an apple – it falls. A theory doesn’t need to be perfect to be applicable.
Sex can be a defense mechanism. You love a rich guy for his money, but you don’t want to think of yourself as money-hungry. Therefore, you develop a sexual longing or even love for that person. Problem solved.
