I don't think that fighting about who is right will help the op. I have seen both: the "left alone piercing" and the "twisted piercing" both ok and infected.
I think there is no general rule, except do not finger it a lot, do not use all sorts of stuff on it (hydrogen peroxide is out in wound treatment, only used to "foam out" dirt in really grubby wounds!), saline solution, either selfmade or bought as suggested in various posts above is really the best when there is no infection.
I personally have better experiences with mildly manipulated, i.e. twisted piercings, but again this is not the be all and end all.
By the way: when was the piercing done?
