Much of this information, if released publicly, would be dismissed out-of-hand as incorrect to anyone who is an upright and decent person.
To the poster below me, the offer of sex can be used as control regardless of acceptance. If a wealthy and attractive person offers you sex, and you are unaware of an ulterior motive, the mere act of offering does factually impact your psychology and changes your cognitive biases. If the changing in these biases is directed, you are being controlled.
I recommend brushing up on your espionage knowledge. This isn't magic, it's intellectual honesty.

Everything impacts your psychology and changes your cognitive biases. In that broad sense of the word "control", we are all "controlling" each other every day, no sex required.
