So it's a good question to think about between when is a problem using porn from when it's not a problem using porn, so because I think alot of people have that question. So we come back the definitoin of addiction, so someone has lost control, somebody has consequences, and they cannot stop because of the consequences, then it's problematic. And the consequences that we're beginning to see with long term pornorgraphy use, and it could be short term like three months, but using it all day and all night, is that people start getting aroused only by the pornography image and they become not just sexually aroused, but they have hormomes released in their brain that causes them to be attached to the image. They feel in a relationship to the person. And now they have somebody on the screen who is a perfect fit for their idiosyncratic fantasy and they've unlocked the key to a very specific fantasy that had been lurking in their brain, and now they can't get interested in anybody else. And so when their wife, or husband, or girlfriend, or boyfriend is interested in being intimate either sexually or otherwise, they start being not only disinterested, but turned off. They can't even get aroused anymore in many of the instances that we've seen. So when somebody's using porn, whether you use the word addiction or not, we have a person who has had severe consequences because of porn use and we have people reporting to us that when they try to stop, because they start to realize that they've gone too far, they start being intruded on with these porn images that they can't get it out of their memory banks. So addiction is a memory issue. The more you expose the brain to erotic stimuli, the more the memory system collects those images and pretty soon, because of the hyperaroused states, that's all you're interested in. And so the person you've loved for 40 years, or 40 days, you don't feel in love anymore with them. The brain has been altered. The good news is, is that, that can change, but it takes time.
