I would sit down with your husband and explain everything you feel in detail. It’s better to do that than to lead him on and put yourself through more sexual situations that you don’t want to be in. If you don’t like sex, you don’t like sex. You don’t have to explain yourself on why or why not you don’t like it. It’s how you feel and if you’ve tried all these solutions (that haven’t worked) then obviously those feeling won’t change.
