Do you ever really forget what the P looks like?
This is just my opinion, but no, I don't think you ever 'forget what it looks like.' However, I do believe that over time, those mental images have much less power over me if I stay in recovery.
Even as I sit here now--if I conjure up a sexual image in my head, it doesn't arouse me
nearly as much if I had an actual image here before my eyes. Also remember, a lot of porn addiction is about novelty--and if images are already in the mental image bank, they aren't novel anymore. It's hard for a PA to generate, within his own imagination, images that will produce the same kind of dopamine spike that
actual porn triggers.
As far as other triggers, those might be all over the map. I'm personally attracted to a certain body type, and women who fit that type will always catch my eye--I don't think porn has much to do with it. As far as a particular porn star's image or name ... well, I think we're unlikely to come across those names unless we're actively engaged in porn. Sure, porn is somewhat mainstream, and stars' names get tossed around in the media a bit ... but it's unlikely that a personal favorite would ever pop up. Certainly none of mine have, and I have several.
I have two highly sexual ex-girlfriends who each bore a striking resemblance to two different celebrities. Whenever I see those women on the cover of a magazine at the grocery store, it triggers me and I can't help but have flashing thoughts about those experiences. But they don't send me into the rabbit hole anymore ... I don't walk away and spent the next two hours daydreaming about them, you know?
So do we ever 'forget'? No ... but it does get better.
