I don't completely disagree except all it took was a "well...I didn't really want to." as an afterthought, when at the time there was VERY MUCH consent.  The "gain" that you speak of is peace of mind for the person, or justification that their "actions" don't garner them a label (slut, whore, whatever) after the fact.  As I mentioned I witnessed someone try to "change the story" after the fact because the relationship they wanted turned into just a one-night stand (well a few-nights stand).  

This may not be the case, but I can certainly see this scenario playing out.  And to be clear I am NOT saying it doesn't happen, I've witnessed the "sports parties" on campus.  I can assure you many despicable actions get swept under the rug by the University administration concerning their athletes.  I'm just saying "1 in 9" seems pretty high.
