I struggled a lot with Dr Suporn's dilation regime in the beginning too. I don't know what to recommend at this stage if the dilators wont go in, but from what I understand, that width can be returned with more dilations. That's they key. If things are getting difficult you need to dilate more often and for longer, even if you can only use fingers right now.
Try going to a sex shop and finding a thin dildo if you can. It's not the best option but it's something to start with. Make sure it isn't rubbery, you don't want any friction.
Use a LOT of lube! (I used heaps in the first six months).
Do NOT give up!
Double the amount of time spent dilating (I did this when I was having troubles).
Push hard! Especially when doing the stirring motion! Dynamic dilation has different goals to static dilation. Suporn patients can develop scar tissue that can tighten and restrict dilation. The aim of dynamic dilation is to stretch that tissue.
Oh, and always listen to the advice of Sophie and the Clinic, and always stay in touch with them. They have dealt with every possible scenario before and know the best ways to move forward. Do NOT rely on the dilation techniques or post-op care instructions of ANY OTHER SURGEON. They are tailored to meet the needs of those ppatients only. This is a different surgery with different requirements to heal well.

You can do it!
