I underwent the procedure last week. There was length loss of about a quarter of an Inch, but that\'s because I measure from my fat-pad, which was swollen and therefore raised at the time. By the way, I had the worst swelling of any photos I\'d seen on here.
On the 5th day now, and it\'s almost reverted back to it\'s original coloring, with the exception of some dark purple areas. I will try to post some pictures as part of my general progress.
I had around 6cc\'s injected around the base this last session and it took 3 weeks to get back to my normal length.
Give it time. Barring infection (which you\'d know about) there should be no reason for permanent loss of length.
Well, I suppose if you had enough PMMA injected that your penile skin was stretched so much that your penis was unable to extend fully, but that would be correctable with moderate Hanging or stretching exercises, one would think...
