You certainly can control someone by offering them sex - it's a well understood and successful tool used in espionage.
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.
>the mere act of offering does factually impact your psychology and changes your cognitive biases.
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.
I did not say that there are no women who use sex to control men. I said that it is not possible to control someone merely by offering them sex. It requires the cooperation of the person who is being offered sex. This is in stark contrast to the kind of power older men often have over younger women.
>And the idea that we can just decide to switch lust on and off is ridiculous.
Who said anything about switching lust off? All you have to do is decline the offer, which is eminently possible.
Edit: I can no longer reply due to the thread length, so here is reply to below post:
To say that someone offered you sex, is to inculcate the idea of a sexual relationship with a person which you would otherwise not be associated with in such a context.
