She's had 2 kids, no stitches on the 2nd, and she can take 6.5" like it's nothing. I think I've reached my limit, but she's pretty far from hers. We may go that route instead.
I think that's a perfectly reasonable solution. I'm not sure when's the last time you used a condom but you know you are Magnum-Certified now right? Possibly even Magnum XL. I mean I think you've held up your end of the bargain, besides, vaginal rejuvenation is a thing. No shame in it, much like how you felt comfortable doing this procedure yourself.
The real challenge is how to approach the subject matter. Just like we can be sensitive about our sizes if a lady makes mention of it, they are equally insecure if we point out how "cavernous" they are/have become. You know your wife better than anyone I'm sure, either she'll be a team player OR she'll need to be brought into accepting the idea gradually.
I'm not suggesting you rule out additional
PMMA, but if she can handle 6.5" readily like you said, wouldn't additional procedures be an exercise in futility?
