I don't think there's anything wrong with a 12g initial stretch if you've had pierced ears for a while. At 19, I went from standard gunned lobes [that I have had since age 9] to 14g, which slid right in with room to spare. As a matter of fact, I had worn 14g circulars for periods of time throughout my teens and didn't even consider it "stretching", because they slid in like "normal" earrings. I probably could have started out at 12g. It is good that you ordered the 14g kit just in case, though.
As for aftercare, I'll sea salt soak twice a day for a couple weeks after a fresh stretch, and wash with Satin once a day in the shower. Then, I'll give them a good jojoba oil massage every night. Once I've been at a size for a few months, I'll go naked for periods of time.
One thing I don't get... I've read that you shouldn't use jojoba oil on fresh stretches. I lube my tapers with jojoba oil, so why is that bad? I'll even put a little more oil on my clean fingers and lightly massage my lobes after a fresh stretch, and they like that a lot.
