When I did pick up the habit for a while after I had kids, I noticed a marked decline in my interest in putting out "effort" to have romance when a video would suffice.
I found porn made me lazy, not impotent. Anyway, cutting that out has been really good, it makes me have to work to maintain a healthy relationship with my wife.
This is obviously anecdotal, I went through a lot of changes in that time period as well, not working out as much, having kids, etc. But it's a little thing I can control to make life happier.
Its to the point that I can't sleep well without it. That's bad.
What I'm doing, right now, is to create a simple chart of the days that I venture to the "dark side". So when I do go, I know in the back of my mind that I will have to write this stuff down.
Another step is, when you find yourself going down that rabbit hole, to do you best to stop it immediately. Your mind is very clever at making excuses like "You deserve to see this. Its just this one time. Promise." For me, what I ended up having to do is to get out of the room of the device and let myself relax.
Its getting warmer out. So I'll probably take a walk around the block if I notice the habit returning. I want to get rid of it so badly.
Support groups are out there either virtually or in person. Perhaps that's another way to go about it.
Good luck!
I would say that anyone who thinks porn isn’t affecting them should try to quit fully for a few months and see. It costs nothing, and you might find out that you have less control than you thought. The effects can be more subtle than what is mentioned in this article: for example constantly craving for novelty despite being in a good relationship with someone you love.
