I hope too much time hasn't passed yet, I might be too late.
Dear DenAm,
First I'd like to adress this thing with your husband.
For BOTH of you, things are not like how they seem, so I hope you haven't been done anything you'd regret yet.
Your husband is not gay. And both of you are actually pretty normal in behaviour.
It's just that the conditions are a bit difficult.
Both of you and your husband have had a rasist upbringing, and that's your husbands hidden reason to watch this kind of porn almost exclusively. He is dealing with his rage towards black men. He is dealing with his the feeling of INFERIORITY that comes with racism...
Why do you think the white rasist always shout "white power" etc. ?
It's that they feel afraid at some level and try to boost their own, like school bullies.
The rasist thoughts come from mostly upbringing, but also the unability to connect with another group of people. And for multiple reasons, you feel intimidated on some level or many levels. That's when you get inferiority and hatered. There are other reasons too for racism, but clearly your husband deals with these kind of things.
Heck, even I have viewed this kind of porn and felt turned on. And I'm not a racist, nor I ever would like that to happen to me if I was the white man, NOR the black man... it's just that the fantasy is so animalistic and wild. There's a big theme of alpha man power in there. Another man submits just to watch when his lady gets dominated by the more superior man. The fact that it's a black man is just your racist background.
This fantasy is just a power fantasy. It's not gay fantasy for your husband.
I think that fantasies, especially this magnitude, come from sexual powerlessness.
You told that you felt bad watching these... only after when you started looking at it, you started to enjoy the forbidden fruit effect.
It's natural for you to link sexual pleasure with large penises. That's completely normal. Especially when you link it with "never had it", it's even the bigger source of desire. You think that a big penis would automatically make you have a great sex life.
That's not how it is.
You and your husband struggle from bad sex life.
I know from experince when I started masturbating to porn while I had a girlfriend while she was sleeping... I felt limited with her. It wasn't like I really wanted the things I saw in porn, but our sex life had started to follow the same pattern, and due to some mishaps, it had been narrowed to certain area of sex... let's say if I really wanted to eat her out, I didn't feel like she enjoyed it much, so one of my needs that I really liked to do stayed unfulfilled, so I channeled this unfulfilment towards porn. Didn't matter what, it felt like I was getting something I didn't with her.
Our sex was great, but it was enough to suppress just tiny bit.
Oh, another thing was that I was a bit unafraid at the time to take the sexual initiative with her.
Maybe your husband feels a bit powerless sexually with you...
Have you rejected his approaches maybe little bit too many times?
I know that if in a normal heterosexual couple, the man feels that he CAN initiate and dominate his woman in a healthy way, BOTH of the people enjoy the whole sexual relationship really much, and I think deep down this is the key for your issue.
You have told that you have lost your interest towards your husband to this craving...
And this craving sounds just the natural craving of a man who ravishes you just right.
That's why you seek strong black men as you link them with this ability. It's also the racist ideas from your childhood that adds to the factor, but racism isn't the biggest thing.
I think your issue is that you feel resentment towards your husband for watching porn instead of him taking charge on you and riding to the sunset if you know what I mean..
One new thing to you if you want to save how things are.
Clearly, your husband lacks the psychological tools to make situation better and I don't blaim him. These issues are extremely complex and difficult to see, especially first hand.
So even if it doesn't really make you feel like a woman right now, I think you should try to make your husband feel OK to dominate you like you desire.
HE has to be in charge once again.
With his porn he is dealing with feelings of inferiority.
He doesn't feel like the man he should feel in order to give you a good time.
Even if you don't feel like it, but you really want to help how things are, maybe you should be a woman to him first... maybe you should put something nice on and let him know in many ways that he is the man... boost his ego some bit in your best chosen areas, especially the ones that relate sexuality.
I guess that if you had a confident, sexual man in your arms reach, you wouldn't be fantasizing on those other men anymore that much, wouldn't you?
