HI dhammapal and anyone else who is seeking to understand the attraction of porn...
I'm not suggesting that you actively seek out porn to test this out. But if and whenever you find yourself engaging with porn, perhaps you could inquire into how you are relating to it. Rather than only
assume a certain subjective position in relation to what you are viewing—that is, treat what you encounter as representative of certain kinds of desiring-persons and yourself as another kind of desiring-person desiring those other desiring-persons—perhaps you could also
try to be aware of the various 'aggregates' that make up your experience of porn: forms, textures, colours, lines, rhythms, movements, sensations, sounds, vibrations, ebb and flow of feelings, thoughts, mood, tone, intensity, and so forth.
Whilst you work on strengthening your resolve to one day fully abstain from it, it may be helpful to 'de-solidify' the experience. Perhaps porn—regardless of what it involves—is not as 'fixed' or 'necessary' as we have been conditioned to experience it.
