Seeking variety in physical appearance is commonplace in fantasy, although I must say those two do nothing for me.
But porn is largely about attitude: as a viewer, you have a sex-positive virtual partner who's comfortable in her skin and takes it for granted that she is desired, that you want what she's got. And she's going to give it to you right now
, playfully or in whatever posture turns you on. That right there is far hotter than a nice figure or a pretty face alone.
A porn actress might
have those things as well, but she is never
painfully shy, insecure, selfish (except in a teasing way), passive, prudish, pious, judgmental, mad, distracted, or bored--all of which are major turn-offs.
I'm bringing this up because the gestalt of your posts here suggests a need to remake your H's deepest thoughts and instinctual attractions. You don't just want him not to cheat or flirt or watch porn; you literally want him not to desire any other woman sexually:
I don't want him to desire anyone else in that way I just want to be his only desire. Of course it's normal to notice attractiveness but I don't think it should go beyond that.
I'm sorry to say that just isn't how the engine works for most guys. However collaboratively you try to shape his porn use, and however much of a yes-man he's become (having been caught and chastised), you're still essentially operating from a position of consuming insecurity.
That's a problem because it isn't attractive and it's also futile: you can't ever really be sure of a person's thoughts, let alone control them. But if you re-frame without the fear, accept him as he is wired (while also noting that he has freely chosen YOU), take his desire for you as a given, and continue your sexual adventures confidently, you can co-opt and dominate his fantasy world rather than set yourself up as a disapproving authority figure he has to hide his inner life from.
