I don't think they meant that rapists do it so they can feel a sense of control about giving their victim an orgasm or not.
My comments were more directed at your statement that you believe that the "giver" has no power. I offered up a direct contrast to that opinion. I was not referring to rape when I made my statement.
But based on what I can gather from the article, I'm assuming this particular woman gave this guy head because she gained personal satisfaction out of the act itself. Control was one of the reasons someone else mentioned, but far from the only excuse/reason.
I remember a court case in Michigan (I think) about 8-10 years ago where an orderly was going into coma patient's rooms on his night shift and giving them blowjobs. Similar to the woman above, he certianly wasn't doing it for the victums(?) pleasure, but rather his own. Do these types of people get off on the act or the circumstances? Who knows really, but I wouldn't rule out some sort of weird mental power trip as a contributing factor.
The problem is, we're trying to apply normal human thought processes to what is probably a unique situation with kinda disturbed people. I say kinda, becuase it's not like they're out there killing anyone or violently raping people in the streets. It seems like a very passive sexual dysfunction where they feel there is no harm done and helps them sleep at night.
But really, wtf do I know? Just making conversation really.
