My honest to god "big moment" was when I first realized my little storm troopers where being destroyed en mass. My semen was turning clearer and I freaked out and started a thread about it, "Standing on the precipice of infertility..."
I was terrified. That was when Evelyn knew ->-bleeped-<-z gettin real yo!
My second big moment was looking in the mirror and noticing the "starry eyes" effect (nod to jennygirl for the term) when your eyes change, open wider, look more glossy and attractive.
Wow.
That change was surreal and weird. I mean the eyes have it, that's your window to your soul for xist sakes. That's going to be a big wtf moment to process once you see it for yourself. You're now seeing 'her'.
My third would probably be my skin. Yeah, it smoothed out real nicely.
