I wish you good luck! The best I can offer you is some advice considering I've had the peritoneal method done (As a revision, attached to the previous penile inversion).
Dilatation is way less intense, I do it twice a day seeing as it's been about 2.5 months since my surgery. However, very often it happens that I skip a dilatation, I've even done once a day for almost 4 or so days in a row, I didn't get any tighter at all or felt changes.
It's very wet, expect to need pantyliners, but it's not so wet that you'll need pads, the wetness coming from the peritoneum is a thin liquid, doesn't really smell like much, just smells like "wet" and at times it can have a slightly (extremely slightly) red or yellow hue, this is mostly due to it mixing with some remaining urine or blood.
As I am the very first one to have this done in my country, we have been establishing a protocol with my doctors based on my case. We've concluded that the best kind of dilator for this procedure is silicone, the peritoneum is quite fragile and doesn't require all that much dilatation. It becomes less fragile over time as it begins to morph into something ressembling vaginal tissue, but for those first 3 months, silicone dilators are very comfortable, less risky and dilate you more than enough. Do bring this up with your doc of course!
Mine was done laparoscopically, so I have laparoscopic scars, one in my belly buttons that's invisible, 3 more around it, hidden by panties, they are 1/4 inch incisions.
Anything else you might wanna know, please do hit me up I'd love to share as much info as I can <3
