[NSFW] How has porn affected your life?

This question is related to a question I asked earlier: How does masturbation affect a romantic relationship?

My brother introduced me to porn before I was a teenager. I’ve had a tumultuous relationship with it ever since then. In many ways, I wish I had never encountered the world of pornography. Yet, I know I’ve learned a few things about myself and about sex because of it.

How has porn positively and negatively affected your internal life? How has it affected the way you relate to others? To your lover?
