Is someone here who never watched porn/magazines but still being a sexual person?

I am very curious about the effects of porn on the brain . I've always heard of very horny people who started porn from teenage-hood or asexual people who get disgusted about the idea of it but never of someone who has a functioning libido who never watched porn.
I would appreciate all of your inputs.

 

My wife and I have always enjoyed watching porn even with other like minded couples
Over the years ones taste in porn matures and from initially just watching WMWF porn we graduated to threesomes MFM
group sex and cuckold porn
WE now watch interracial porn like Blacked.com
Of late my wife enjoys watching Zebra porn with three ebony girls having their way with a white blonde girl
We have found the watching porn fired our libidos and we have had great sex while and after watching
Apart from stimulating the visual and auditory senses I am not aware of any brain damage or aversions

 

I am 40 years old, I hardly watched any porn. I tried to a few times, years ago but never saw the appeal. I have always been a very sexual person even though I have only been with 3 men. However the last 2 months or so I have watched it about 4, maybe 5 times but one time was for 12 hours, the others not nearly that long. I can still say that most of it isn't that appealing to me mentally but my body still reacts to it. I have a tendency to critique them and I know that I could do so much better

 

I go through phases where I want to watch porn and phases where I do not.
I tend to feel like masturbating to actual fantasy is healthy because I am like acknowledging that feeling. It's not just gasoline on the fire.
