There are two groups of people who are agitated over porn - feminazis and religious conservatives. I'm assuming you're not a feminazi, so let's just be honest about that please. What is interesting is that the religious conservatives now have to rely on bogus psychology to make their case against porn. There isn't any clinical evidence for any of the horrid effects of porn that the religious conservatives usually claim.
Now there is such a thing as sex addiction, but there's no evidence that porn causes sex addiction and significant evidence that a bad relationship to sexuality (e.g. being raised in a very strict religious environment) has a role in developing sex addictions.
