So it makes sense that he can manipulate it in such way that he doesn`t injure himself even on contact. I agree. We've seen a similar thing with Kakashi/Obito. Even though Kamui can hurt people, Obito could simply negate its effect. Given that Kakashi was in fact teleported by Obito, this implies the reverse is not true.

So yea, i'd say that the control version of the eye (e.g. Obito's eye controls Kamui, Kakashi's projects it. Amaterasu projects all-burning flame, Kagutsuchi controls it) can manipulate it in such a way that the user is not hurt by their own power.
