– A blog about helping women create intimacy in marriage. A wonderful resource if you are the low desire wife, but this page in particular is aimed for us who are high desire wives & in a marriage where our intimacy needs aren’t being met. Good stuff here!

Hello. I have read your posts, and I wonder if the Schedule IT idea of Tony and Alisa DiLorenzo might be a tool for you in your situation. You can listen to their podcast, presenting how they did this at: http://www.oneextraordinarymarriage.com/140-scheduling-sex
My wife and I used this to jump-start our marriage two years ago. We went from less than once a month in 2010 to 3-4x a week for the past two years. At least have a listen and see if it might be a resource for your readers to try, if they have generous, loving husbands.
Thanks for the info Chuck. I think a lot of my readers might not be in a place where simple scheduling is the problem, but I will post it in case it is a help to some.
