hello,
i am about two years and have maintained a very steady 5" depth. doctor menard in canada was my surgeon, and his instructions for dilation are daily for the first year, twice daily for the first six months. i cheated actually, because while i was working i only dilated once a day. to make up for it, i doubled up on the time required for a single session.
i am supposed to dilate at least once a week for the rest of my life. i try to do it at least 3 times weekly, but i have learned how to enjoy it. also, i like being with men, and i like big ones. sometimes it can be a little painful, and i can be sore afterwards, but if i am seeing a guy i just don't bother dilating. either way, it has become a pleasant experience.
