Using coroutine to change current GUI

Question

Hi, as the title try to say, I have to change my GUI, specifically, a GUITexture, from time to time. For example: in the first 5 seconds, I have to display the GUITexture1. After this, for another 5 seconds, I have to show the GUITexture2. I intend to display this GUITextures to make something like a "Introduction".

So, I've tried to do something like this:

 void OnGUI ()
 {    
     if (messageGUI)
     {
           if (textOpt == "Ligado")
          {
             message = Resources.Load("Levels/General/generalSpeech1") as Texture;
             StartCoroutine(showMessage(message, new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y), messageSize, time));
                 
             message = Resources.Load("Levels/General/generalSpeech2") as Texture;
             StartCoroutine(showMessage(message, new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y), messageSize, time));
                 
             message = Resources.Load("Levels/General/generalSpeech3") as Texture;
             StartCoroutine(showMessage(message, new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y), messageSize, time));
             }
         }
     }
 
 IEnumerator showMessage (Texture message, Vector2 position, Vector2 size, float time)
 {
     messageGUI.enabled = true;
     messageGUI.texture = message;
     messageGUI.name = "Message";
     messageGUI.pixelInset = new Rect(position.x, position.y, size.x, size.y);
     yield return new WaitForSeconds(time);
     messageGUI.enabled = false;
 }

But I've noted that this don't solve my problem, 'cause the OnGUI function are always running and the next command don't wait the previous to finish before starts running. I know why, but I don't figure out how could I do what I want. Any ideas?

Thanks in advance.

Yeah, thks @asafsitner, and @cawas, for helping even outside the forum.

I could solve my problem with this script:

 void Update(){
         
     introduction ();
         
     if(displayMessage){
         Debug.Log(timer+" "+currentMessage);
         timer += Time.deltaTime;
         if(timer <= time){
             messageGUI.enabled = true;
             messageGUI.texture = message;
             messageGUI.pixelInset = new Rect(position.x, position.y, messageSize.x, messageSize.y);
         }
         else
         {
                messageGUI.enabled = false;    
             displayMessage = false;
             timer = 0f;
             currentMessage ++;
         }
     }
 }
     
 //Levels
 void introduction ()
 {    
     if (textOpt == "Ligado")
     {
         if (currentMessage == 1)
         {
             message = Resources.Load("Levels/General/generalSpeech1") as Texture;
             position = new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y);
             displayMessage = true;    
         }
         else if (currentMessage == 2)
         {
             message = Resources.Load("Levels/General/generalSpeech2") as Texture;
             position = new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y);
             displayMessage = true;    
         }
         else if (currentMessage == 3)
         {
             message = Resources.Load("Levels/General/generalSpeech3") as Texture;
             position = new Vector2(tabItem, Screen.height-avatarSize-2*tabItem-messageSize.y);
             displayMessage = true;    
         }
     }    
 }
