tickledwife, I'm sorry to hear about what you are going through with your husband.
From reading your post, the main problem I see is that he would rather satisfy himself sexually by looking at clips, instead of engaging in physical intimacy, with you, his wife. While I know there are guys who do this on some occasions, if it's becoming a regular pattern, that, to me, should raise a red flag that it's time to have a serious discussion with him, and seek joint counesling. He has a marriage, and a life, with you. If his porn fetish is intruding on that, that to me is unacceptable.
My advice would be to have a discussion with him when you are not in a sexual frame of mind. Put everything on the table. Tell him all your feelings, and listen to his. Then, I would see if some compromise can be worked out, sexually, etc, between the two of you. If not, it would be time for counesling.
I hope this advice is helpful. Good Luck. Hopefully you can come to a workable solution with him, where the more important aspects of marriage and family, will win out over his porn fetish.
