First of all, just breathe and don't over think it. Your plan sounds good. The toughest part is to not get caught up in the stretching frenzy. The piercing will stretch on it's own over time. Follow your piercer's instructions and don't waiver from them. Most of all, once you have it, LEAVE IT THE HELL ALONE until its healed. Wanking, sex, changing jewelry only prolongs the healing. You will have a lifetime to enjoy it, just be good to it while it heals.
Take it slow and enjoy the ride.
