As an update, I will be 12 weeks post op tomorrow. Dr. Chet provides 4 dilators that are the 4 smallest common sizes of dilators issued by most surgeons. I bought, on my own, the "Mr. Green" and "Mr. Orange" from the Sole Source set.
I was planning to start Mr. Green tomorrow, when I hit 12 weeks but I got a little impatient and started Monday. Thus far there have been no issues and Mr. Green goes in up to the last dot and a tiny bit over. Getting Mr. Green into place is like the first week with Dr. Chet's #4 - it takes a couple minutes to get all the way in. This will get easier over time, just like #4 did.
There have been no complications to date, but I've stayed away from self exploration too much, wanting to hit my 12 week mark to give healing as much time to work as I could.
I've begun shopping toys to help me explore this new topography and all the sensations that come with it. I may or may not have comments about that later.
