"I am still not sure how often women simply consider sexual interest to be harassment"

There are lots of ways to address this, but I'll limit myself to probably the biggest issue involved: Power dynamics. If your boss expresses sexual interest in you, it puts you in a very difficult situation if the interest is not mutual. See result #4 in the article, and read through some of the comments here for examples.

Right, what they have in common is the idea that the situation gives the woman less rights. Either she owes the man sex in exchange for promotion at work, or the man can take sex because his position outranks hers. Once the determination is made that she can't say no (or not without a fight), something has gone seriously wrong whether it progresses to rape or not. And yeah there's a spectrum and yeah there are other axes we can judge the situation on, but there's a litmus test here and it's not asking a lot to pass it.
