This is not an easy topic to talk about. There are some really defensive people when it comes to porn. But I applaud you for how well you talked about it. Porn is not healthy for an individual. The porn industry also supports human sex trafficking. So, it's awful for a lot of people.
As a Christian, even a small amount isn't okay due to views on lust. I remember when I had to ask my husband (when we were dating) about it. My heart was about to explode from beating so fast lol. It just wasn't something I would have been okay with. Thankfully, we are very much on the same page.
