Have you had a child recently? My libido was nonexistent for almost three years after I gave birth. I think that it was a mix of emotional and hormonal changes that took place. I have spoken to other women that experienced the same loss of drive. There was nothing that got me excited and I just wrote off sex for a few years. I was not in a long term relationship at the time, so it was easier to be asexual. It is still not easy with the flashbacks that have started, but at least I have a drive.
