If your ask here in this board, you will find a lot of other girls dealing with the same issue.
Many of us felt that we had a lot on our plate to deal with and that the super sexy stuff was not number one in our list. It's probably were we forgot that men is some kind of animal, selfish in many ways and that they need the extra to keep going.
Many, many women (not all I would say), have the instinct of dealing with protection. We are born with survival skills and we get involved in making the best of a household that is secure, business are taking care off, it is all done for the peace of the home, we have food, good shelter.
My mom told me another day that my grandmother said it to her one day too: A happy marriage has a spouse during the day in a house and a prostitute during the night in the bedroom.
My mother also struggled with this same issue. Like I am now, my mom was a wife, a mother, a friend, housekeeper, secretary, gardener, teacher, therapist, accounting... but she forgot to be a prostitute.
I made many mistakes in my M, and the biggest one was this, sex became a second plan, sex became dull, not so exciting. If I ask myself now, I would say was not good even for me.
This is a lesson learned for me. I don't want to take it for granted anymore, instead I want to learn from my own mistakes and fake morals.
Hope you can find balance in what is right for you Toots, there is nothing wrong once in four walls with the man you love.
