hey G., I do some research on the interaction. I read somewhere that the
PMMA can really affect the blood supply to the graft, which can cause it to harden and go fibrotic (and shorten) and then you might have a real mess on your hands. It is going to have to get in between the vascular tissue that feeds into the graft and the graft itself unless there is some other layer that the
PMMA is injected into. Even a healthy graft has nowhere near the blood supply that regular tissue has that you were born with. I would not mess with it without a lot of discussion with a phallo doctor and especially your own research on the subject.
