If a man is studying Torah he can hold postpone getting married.
As for the yetzar hara not getting to him, I heard that men today simplysimply cannot reach that level of being unaffected, considering we are referring to a man who is naturally attracted then he is required to be getting married.
Plus there is the whole a man isn’t a man without a woman and he needs to be married or at least try to fulfill his purpose in this world.
I have heard mixed things. You are a complete person as is. Yet without your other partner in marriage one isn’t complete because the neshamah needs its other half.
