Blocking porn on an adult account

Hello, I would like to block porn when I am on the internet. I don't want to just pretend I am a child surfing using Norton's parental controls because then it invariably blocks things and sends me warnings whenever I enter my age, which is obviously over the age of 17. Is there any way to block porn using Norton, for adults who simply don't want to be startled and disgusted when seemingly innocent websites turn out to be something else?
