Finally got an update to share!
I had a very thorough check up earlier today. My surgeons took me to the operating room, where I was set up. They used a camera, inserted it into me and we were looking at my tissue.
It looks beautiful and pink and moist, from what we can tell, about 3 months after my surgey is that the perioneum is definately strinkingly ressembling vaginal tissue at this point. It is also very elastic, not just in width but in depth too, it's possible to stretch it out just under half an inch or 1 cm at this point into the depth (On top of the originally set depth), this is something new that I at least wasn't expecting to be able to do.
Due to possible fragility, I'll be holding off from sexual intercourse for another 3 months, I will update this topic periodically and of course update it once I've had my first intercourse so that you gals who might be getting the perioneal procedure will know more about it!
