totally lost my labido

Emma

I am happily married to my husband for 8 years, no kids, great sex life until about 2/3 years ago. I have totally lost my interest in sex, I have no sex drive at all really. I love my husband and I still fancy him, we both keep in good shape, but I would rather just pleasure him than have full blown sex. I keep making excuses and it is starting to get to him. I am only 38, when I was younger I never had a problem, but it's really starting to worry me. I can't pin point it to any event, just lost interest. I do still master bate from time to time, I used to do it alot because I could not climax when we had sex. When we met we both liked dressing up, dirty talk all that stuff. But now I have no interest. What can I do?
