I am sorry I won't be able to provide very specific information because I don't exactly know your situation, and even if I did, I am not sure what the best thing to do is.
In order for a relationship to work, BOTH people have to be committed to making it work. From your description it sounds like he is not committed to making it work at the current time. Counseling is a good idea, but again, it only works if both people are committed to making it work.
Are there any other elements of your marriage or the behavior of one or both of you that are out of line? Does your husband have a porn problem or is he involved in any online relationships or other extra-marital relationships? These are the kinds of things that can make a man very distant from his wife. A few years ago I got involved with some internet porn. My marriage, which had always been great, sort of deteriorated over the course of several months, perhaps a year. I never told my wife, and she didn't know, but she knew something just wasn't right. Eventually I told her. She was very, very depressed for several days. Since then I have worked diligently to stay away from the porn because it makes me darker inside and it creates tacit barriers and tensions in my marriage and in my house--even if I am the only one who knows. The last few years since have been very wonderful, thanks be to God.
Some how you have to find a way to communicate without accusations and criticisms. I don't know the best way to go about that. Many women, and some men as well, have a tendency to nag or constantly be critical or bring up negative things and deficiencies, and eventually their spouses tune them out.
Regarding kinky stuff in the bedroom, that is your business, but great sex in a long term relationship is not dependent on creativity and kinkiness--it is dependent on a great relationship. A great relationship makes for better sex, but better sex does not necessarily make for a better relationship. I have never actually found kink to make things any better in my own personal sexual relationship, but a concern for the happiness of my wife sure does.
My best advice is to regularly get down on your knees and seek the help of a loving Heavenly Father who knows what is wrong and how to help. I would also approach your husband and tell him that you love him and want to make things work. Ask him if he is willing and what he thinks you both need to do. Avoid any blame, even if he starts up with criticisms and the like, try to avoid making the conversation a confrontation or an argument. Just tell him you are willing to work on what you can if he is willing to work on what he can, you're just asking that he be willing to try and make it work. You might ask him if there is anything that is keeping you two apart, or if there is anything wrong with him if you think the timing is appropriate. If he is willing to make it work, then counseling can work.
