Why do'nt you want it to grow?
I told one of my male buddies that it'd be kinda cool to have a cock that just kinda sucks up into my body when not needed, like a dolphin or Brian the dog in Family Guy.
But basically um well, more meat is good. I mean the darned thing pre-T is so small, you can't do much with it. It's so much fun having it bigger, and the fun shivery feeling when it perks up, sometimes for no reason at all. Getting something like a real ->-bleeped-<- is going to be great. Having it grow enough to do some actual penetration, if I am so lucky, is going to be fulfilling my life's dream.
