Accessing a non-static variable from a static method [Java]

Question

What I'd like to do is reference a non-static variable in a static method. I'm doing this so I can have a sort of master control that I just have to run the individual methods in to make my code alot more neat. If there's any other ways to do this easily and/or efficiently. Thanks for your time.

import static java.lang.System.*; 
import java.util.Scanner;

public class InteractiveStory
{
   private int health, sanity, pumpkinPies, dexte, stren, chari, intel;
   private double money;
   private char Gender;
   public static void main(String args[]) // Main chunk of programming, preferably /only/ method refrences. TL;DR, Master Controller
    {
      genPlayer();
      //By the by, need to figure out how to access non-static variables from a static context
    }
   public static void genPlayer() //Begins the character setup bit, gender, name, class, ect.
   {
      Scanner keyboard = new Scanner(System.in); // Initalises the keyboard intepreter
      System.out.println("You are a random bystandard. You are currently sitting in a swively chair infront of a computer. What is your gender?");
      System.out.print("> ");
      String Gender = keyboard.next();
      System.out.println("");

      if(Gender.equalsIgnoreCase("female")) // need to do female first because fe'male'. recognises that even in the middle of strings
      {
         System.out.println("Okay ma'am, what're your skills?");
         Gender = "f";
      }
      else if(Gender.equalsIgnoreCase("male"))
      {
         System.out.println("Okay sir, what're your skills?");
         Gender = "m";
      }
      else if(Gender != "male")
      {
         System.out.println("Oops! Invalid gender. Sorry.");
         System.out.println();
         genPlayer();
      }
      System.out.println("Are you,");
      System.out.println("1. Dextrious?");
      System.out.println("2. Strong?");
      System.out.println("3. Charasmatic?");
      System.out.println("4. Intelligent?");
      System.out.print("> ");
      int answer = keyboard.nextInt();
      System.out.println("");

      switch(answer){
         case 1:
            dexte = dexte+1; //Errors begin here, trying to reference a private variable that is nonstatic above.
            System.out.println("You are now slightly faster than your average turtle!");
            break;

         case 2:
            stren = stren+1;
            System.out.println("You can now lift 3 pounds extra! Now a whopping 4 pounds!");
            break;

         case 3:
            chari = chari+1;
            System.out.println("You no longer scare small children!");
            break;

         case 4:
            intel = intel+1;
            System.out.println("You now have a basis for flaunting your itnelligence to rocks!");
            break;

         default:
            System.out.println("Sorry, not a valid answer!");

      }
   }
}

Make your getPlayer method non static and call it like this

    public static void main(String args[]) 
    {
      InteractiveStory interactiveStory = new InteractiveStory();
      interactiveStory.genPlayer();
    }
