It can take a long time to recover, but you will recover. My porn addiction escalated to transexual and sissy porn, and to the point of developing HOCD (homosexual compulsive disorder). If your desire for this kind of porn is porn induced, they will fade in time. I'm only 23 days into this reboot and almost all of my HOCD has gone.
The 'flatline' can be scary. It's tempting to look at porn to see if your penis is still alive, but don't do it. Try to think of the 'flatline' as your friend. It can hope you stay away from porn because you feel dead in that department. I once 'flatlined' for over 100 days, but I think most guys come back to life before then. Be patient. Don't relapse and look at porn otherwise you just throw yourself right back to day one!
Good luck!
