I agree with Mobius. Some men hide their feelings because they are concerned about how you would react.
I think you should talk to your husband. Tell him what you told us. I betk you'll be pleasantly surprised with the results of open communication. However, there is one caveat: it could backfire and ruin your relationship. If you're willing to take the risk, open up and see the response. If not, be prepared to live a frustrating life.
