I wish I could remember, and that I had kept a journal. I know the spiral began with emmissions changing from milky to clear. That was , I think, toward the end of year two. Then to a gradually smaller and smaller amount, before finally reaching a dry climax. I believe that first occurred for me about mid way through year three. Maybe later. Now I have essentially no libido left. One question I have when I see the endo next week will be if this is hypothetically reversible...not that I want to or care, but just for the sake of knowing. Lord knows, in my time I bet I got several lifetimes of use out of that equipment, so I am not complaining at all.
