Do you think of questions to conjugate words into their correct forms when you speak? No, you don't. You just do it from your experience and from intuitive knowledge of what each case/verb tense/preposition etc. means. That knowledge comes from hearing, remembering and then repeating the familiar constructs over and over again. Over time your brain makes out similarities between different constructs facilitating your understanding of them even further and making it easier to apply them in a wider varity of situations. This is how you learn a language.

Conjugation questions are irrelevant.
