Wait, you're not certain what horniness feels like, but you consider yourself somewhat of a porn addict? Now I need YOU to explain how you feel :P
I've read through most of the comments here and many of them ring true to me. Especially this one: https://lemmy.ca/comment/19383774
I am that pervert. Not outwardly, but inside my head? Yeah. Sex is on my mind often, and I use porn as an outlet to kindle and experience those urges when it wouldn't otherwise be appropriate. I've started taking ADHD meds and a lot of that day to day horniness has gone away, simply because my mind isn't idle as often, and when it's idle or bored that's when it reaches for the junk food: lust. Porn (or sex), when I'm in that state, is the most interesting thing in the world. I could, and do, watch it for an hour or more to draw out the experience because sexual energy is so mental for me. It's what makes kinks so attractive because sex becomes a mind game.
So, with that aside, can you explain to me what exactly you find attractive about porn to the point you think it might be an impediment, if you don't feel really horny? My GF has a low libido and as a result she rarely watches porn, so I'm not sure how the two mix. She also enjoys orgasms, but doesn't seek them, and when she does watch porn to get off she does it quickly and doesn't really relish it. She definitely doesn't have an addiction, but maybe you can still help me better understand her, and other perspectives a little better. Because yeah, in my mind porn has always equaled horny.
