Understood. There are many ways to be a “little wrong” (and that’s really a bad term - because what is right is whatever is ok between the two of you within Church definition.) Loving acts can sometimes, therefore, take multiple forms. Some people may like dressing sexy, role-playing, dirty talk, etc. While it makes sense to work with hubby to “ratchet him back” at the same time work on yourself to determine your comfort level with your own sexuality and why. I think, like anything in marriage, there is often compromise there - today my wife is certainly comfortable with things that she used to have a very rigid view on that is less rigid today, and there are things that she is still rigid on that we discuss. (A simple example is why is position A ok to some people but position B is not.)
Your willingness to TRY to be flexible, even if you cannot be so in the end, will likely fuel his ability to be flexible and come more within your comfort zone; it develops a feeling of acceptance in a man, which is really important to men generally.
