Some form of dilation is a good idea but after years it becomes less important. At some point, once a week is enough BUT if you are sexually active, that can replace dilation. After 20 years, I became over busy and kind of forgot to dilate for about 10 years. It was a bit uncomfortable restarting and it took a few months but I am back where I was before. I have never been sexually active so there was nothing maintaining my size for the years I missed dilation.
