Quote From: debbyl950HI,  
I am married to a wonderful man, he is my best friend. He told me when we were first married sex was over rated... that hit me like a blow in the head. I knew his dad was warped (had him in a threesome with his girl friend and him, guess to make a "man" out of him, he was not even 15) and your dad is usually your role model, but he is not like that, not at all. He is the kindest man, he would not hurt a flea or be cruel to anyone.  
We have been married 7 years and I have been very patient with him. I try to wait until he is in the mood, but I don't think he ever really is. I think the only reason he has sex with me is out of duty. We are able to please each other almost every time and I think we are very fortunate for that.  
This year we have had sex 6 times, less than once a month. I would be happy with once a week, I would really be happy with twice a week but would take twice a month and be very happy. Really, I wouldn't mind it not being so often if I felt like he truly wanted me. Truly wanted to make that union with me.  
I try to get him to talk about it, he finally said he had things in his head but he just couldn't get them out. I have been patient and listening (instead of talking) but he does not want to talk about it.  
He did make the statement that our relationship couldn't just be about sex. I agree 110%. The ceiling fan was on in our room, I said, "Do you see that fan"? He said, "yes". I told him if that fan got out of balance just a little but we continue to run it after a while that fan would wobble more and more, not because it started off so off balance but because we continued to use it that way".  
Still nothing, he works very hard and is always tired. He is over weight and so am I, he gets very little exercise puts in extra time at work and comes home and does marketing for home based bushiness he is trying to get started. He has time for what he puts first, I just don't happen to be it. I have told him that but try to be kind in what I say.  
We enjoy hobbies together and spend most of our time together... we love to be together. I feel like a dog waiting for a pat on the head. I feel like he looks at me and thinks.... "good wifey, good wifey, now lay down and be a good girl and go to sleep". I keep a clean house and work full time out of the house. This is not a new problem... and the fan blade is really wobbling. I feel it is just a matter of time until we are just room mates trying to live out our lives the best we can without hurting each other, and that is very sad.  
It sounds like you are married to a wonderful man, and I am sure he has some hidden pain that is not willing to share with you, not because he doesn't care, but because he is a male, and our egos are bigger than we would ever admit to being.
If his father did what you are saying, you don't know what else may have gone on, that he keeps hidden to himself. There could be some deep dark secrets that you would be the last person he would ever want to share with, because you are the one he wants to look up to him for support.
Instead of him telling you, maybe you should try to talk to him about talking to someone else. You need to do this in a non-threatening way, where he does not feel judgment is being made of him in any way. This needs to not be brought up when sex may be an option of happening. Maybe at a dinner table or while sitting and listening to music or some time where he would not feel he is being under the gun, so to speak.
Again, our egos are big, and we have been trained in our society to be without feelings, and crying is for women, and such. We have socialized our males to hold things inside, and not discuss such things. This, little by little is changing, but for many, it is the ONLY way of life.
His problems could be physical as well as emotional. Has he ever had problems with erectile dysfunction (ED)? If men have problems in that area, discussing it with the one they are making love with would not be easy. He could have a low testosterone level, which diminishes the sex drive as well.
Talk to him, again when there is no pressure, and ask him about going in for a check-up and get his testosterone levels checked, and talk to him about talking to his doctor about how things are going in this area. If it is due to some sexual trauma, see if you could get him to go and at least talk to a therapist. Sometimes it is easier for men to tell a complete stranger, that they are not going to have to look in the face every day, if they think it may help, than it is to tell the one we trust and love with all our hearts.
I hope this helps, and I hope it gives you some ideas. Good luck, and great sex!
