From what I've been told by people in high positions, they get women throwing themselves at them all the time, some just for the reputation that they bagged the boss or a person in a high position, others so they can get leverage to use at a later time.
A general once told me it was part of their pre-general promotion briefing (for males and females) as it is a real issue.
Some heeded their training, others succumbed to temptation and lost their career as a result.....sometimes many years later when it was convenient for the "wolves" to come out of the woodwork...it's a pretty hard thing to dis-prove if there were only two of you as the female is always believed.
Once I got to a certain rank, I distanced myself from these sorts of threats and if at any time when I was to have a female in my office for whatever reason, I always brought in a buffer person...I made sure I was never alone with a female at work.
I saw this at work with a peer who was close to his female subordinate and the minute he pissed her off....she cried sexual harassment.......we all saw this coming and warned him a couple times but his attitude was that she was not like that........she was and his career took a real nose-dive even after her allegations were proven false, once that sort of thing gets attached to your name, it stays with you....
