Sounds like you have a seriously cool GF :-)
Restoring takes time and patience as I'm sure you know if you've Googled and checked out the various blogs.* But IMHO it's worth it.
You know, it would an interesting project if you started creating content now with your cut dick and then as you gradually gain coverage create some more content every couple months. You could do time lapse photography just of your dick and do videos with your gf jerking you or whatever as you gain coverage and keep notes of how it feels. Then, once you're fully restored you could splice them altogether into a XXX documentary.
Just an idea ;-)
*which reminds me, did anyone see that TV show called 'Single White Penny or speny'? It's a comedy version about what can happen if you try to restore too fast.
