@Kandylove,
Considering todays statistics of porn regular usage and also addiction... more than likely true, yes. Just statistically, the friend you talked to about it has probably been into porn as well, no telling how deeply. But the fact that you're with your boyfriend, and you're attracted to him... it means there's something within yourself; a psychological issue, probably related to miscommunication or being afriad to speak up, and also with connecting on a non superficial emotional level... which makes you attracted to him. You both need to reconnect on a deeper emotional level and talk about these things. You need to talk about how you feel hurt and degraded to him more directly. He needs to be more open and honest with you about his guilty feelings. You both need to try to be more emotionally... legitimate and connected, on a daily level. Make sure you do this in a mature, understanding way. Try to have insight. Don't demonize him or you aren't gona get anywhere. Together you can both learn from eachother.
I don't think impulsively leaving or withdrawing sex is a great solution .. it's an avoidant tactic, but you will be running from yourself just as much.
