He has found a different IC who specialises in sexual compulsion
This is a really "wild" speculation because I do not understand this change myself yet, but maybe it would be helpful to understand what is going on with him. I will try to keep it within the boundaries of decency seeing the topic.
Starting from the obvious, you know how we guys work, it is visual first emotional second, that's the trigger of attraction and sexual desire.
However I am starting to believe in a healthy relationship the visual part should be following the connection to the woman who is your partner, making it deeper.
What do I mean with this: after getting out of PTSD and trauma I had several changes, not only psychological, but also physical, all for the best, even if some like this one, are confusing.
Now, usually with puberty you start to "discover your body" with all that follows.
It's both fascinating and confusing, so of course your peers talk about that.
At last you make the connection "that's how it works with women" and that's another mystery to be resolved in the years to come.
So that "mystery part" (that you will discover only once you get biblical with a girl) with the hormonal changes and the shock of puberty, with a huge spike in testosterone that grows your body as a bamboo shoot and also skyrockets sex drives hundreds if not thousands of times (literally, chemically not figuratively) spawns the first "fantasies".
How do you deal with those fantasies? Self stimulation is the first discovery, but then someone will talk, maybe sneak up naked ladies (everyone wonders just 'how are they made for real?'), and slowly you get into pornographic material.
That's likely the first contact with that stuff, right when you are into your most confusing time of life, the biggest change.
So of course mix "fantasy" + "Imagery" = Dopamine Reward --> that's the earliest crystallization of Male sexuality.
And still in complete clueless ignorance on how it truly is, because all those things are acted not real.
This might be the moment when the brain makes the first association with porn with some kind of mnemonic algorithm:
Secret, Shameful, Weird and Confusing, but also Exciting, Pleasurable, Shared by peers.
And it's the sharing part that makes you feel less weird, you understand is "Normal" it is 'hush hush' topic but peers talk about it among the group, it makes you feel just normal (and people with low self worth issue might connect to this feeling stronger than your average teenager).
Add to this that the "activity" is both pleasurable and free of charge, and you have a recipe for a great brain hooking (dopamine.... and it's free as you like! wow!).
Still is bad and shameful, you do not talk about it, is a shared little secret, and growing up you still know almost everyone shared that same feeling at some point in time.
But: when you are feeling down, that 'activity' is great for self soothing. If you are in a relationship you know how good sex could be to make your mood better and drive self confidence up. That also works in "solo mode" sometimes is the only 'medication' a teenager has.
Now that's my speculation. Once you finally discover a woman, and you establish a relationship, your reaction should be "Now I have 'the real thing', fuck that stuff for losers, I don't need it anymore".
However I am not sure this happens often. Or better it does, but not to a full extent, you treasure the real thing way more, but is still "real" vs "the fantasy you discovered while in the most vulnerable state of your life".
Reality does not fare well vs fantasies.
Even if you are fully satisfied, there might me moment when that cannot be or simply is not on the menu, and you get "the fix" with pornography.
I speculate, but being one of the largest business in the world, I believe I am not shooting that far off.
To my knowledge every guy I know consume to some extent pornography. It may be more or less of a rarity for most, because addiction is seen as "loser", but is mostly considered ok either as 'hush hush' or sometimes even with your partner if she is in the mood.
Fantasies will always have roots on our choices.
While it may seem I discovered the hot water here, because everyone knows this is obvious, my today understanding is about "the fantasy" being the main driver of it all.
Because when I changed I completely lost that ability, it just has zero effect on me or my sexuality. I was even thinking it might be some medical issue, but no, the "real thing" works fine (even incredibly better than before), is the fantasy or self soothing that lost all it's appeal. It just has no effect anymore, nothing at all.
I imagine exiting the trauma brought with it the death of the old fantasies, and a different embodiment of sexuality that is grounded in presence and the moment instead of the realm of mind and insecure childhood emotions. And I like that much more than it used to be.
So conceding this speculation of mine holds any water, that might be what your husband is experiencing with this addiction: stuck in a teenager loop of insecurity and fantasy that keeps an open void not because you are not enough to fill it, but because he does not want to step out of his teenage room where he is soothing himself up to be able to muster enough courage to show himself up to you and the rest of the world.
It might not be any physical or metal issue at play, more of a traumatic psychological issue that makes him to behave "not like an adult".
Like I said, the whole thing is still a bit confusing for myself, because I never heard of another guy experiencing this, so I might be completely off. It's a shot in the dark, but maybe a facet to consider to see if it resonates with him or his therapist.
