TAL reading about your situation on someone else's thread, and
given the more information on your husband, I would be very
surprised if he doesn't have sexual compulsion issues that are
tied to escaping into fantasy and porn use as an "escape hatch".

It's not that porn and fantasy are necessarily bad things but their
use can impede actual intimacy between people for many. I think
of it as people become tend to become "sexual performers" performing
stunts and tricks while they ignore the idea of being "sexual partners".

It maybe that some of your feelings may just be a reaction to your husbands
sexual acting out.

I hope that both intimacy and eroticism can exist in a marriage
but know it is difficult to balance the two.
