I have been following your threads. I feel like I am in a similar situation as you but that you are a bit further along than me. I have had problems in my relationship and thus sex became very infrequent and also not nearly as exciting as it once was. I think (or hope) we've made some decent progress fixing the relationship issues but our sex life hasn't recovered. And it hurts. It was my birthday this weekend. When she asked what I wanted you can probably guess what I said. She giggled about it and seemed agreeable at the time but my birthday passed and nope - didn't get the present I was hoping for and wanted most. Bumms me out major but I doubt she'll notice and don't really think she cares if it does.
Keep working at it.... your giving me some hope even though I have less than I wish I did.
