Freud has been dismissed these days but that is a mistake, in my view. The power of the libido is just about overrunning the culture. Women are half undressed, men set the stage. Suggestive ads for their issues are all over the place. Women must be blondes, long hair, plasticized, squeezed into their skimpy clothing. Passion, no, lust, is the order of the day.
In my view, the culture has gotten to you: your husband is not enough. You might speak to your shrink and hope he is decent or you have an even bigger mess on your hands. Of course, this has happened before but it is my thinking the environment makes it even harder today. You could also have a talk with your husband. Just my thoughts. Wishing you the best.
