No. I'm saying that just as we see this more often now because people are desensitized to anything sexual. Some people (not most, obviously) don't compute quite right with that shit in their heads. The same as with people playing video games and then going out and shooting people. In spite of BBD's denials, there clearly is a link between our overexposure to violence and even acting it out in games and the way kids behave. It's obvious-- much like smoking and cancer. The oversexualization of society is going to have side effects like more people not respecting private areas of the body. Whether they act out in such ways that are more generally accepted, such as by becoming sluts and manwhores, or less accepted, such as by shoving pencils up assholes, the seed is planted.
As to whether or not there is less rape due to porn, I have no idea if that is true. Honestly, it doesn't make a lot of sense. You don't need porn to rub one out and rubbing one out obviously doesn't satisfy the mind of a rapist. On the other hand, with more women becoming highly sexualized, it's easier to get laid. There would seem to be some logic in more people getting laid equating to less rape. I don't think that has much anything to do, however, with the humiliation and violence involved in shoving a pencil up somebody's ass. That act seems to be a mix of everything I've mentioned regarding violence and sex.
