Can you refactor the IFs into a function, returning at the appropriate point (early if necessary). Then the control flow will pick up in the loop at the right place.

Though it's a bit complex and just a fake, you can use exception this way :

DECLARE
  i NUMBER :=0;
  my_ex exception;
BEGIN
  FOR i IN 1..10
  LOOP
      BEGIN
         IF i = 5 THEN
            raise my_ex;
         END IF;
         DBMS_OUTPUT.PUT_LINE (i);
      EXCEPTION WHEN my_ex THEN
         NULL;
      END;
  END LOOP;

END;

You can simulate a continue using goto and labels.

DECLARE
   done  BOOLEAN;
BEGIN
   FOR i IN 1..50 LOOP
      IF done THEN
         GOTO end_loop;
      END IF;
   <<end_loop>>  -- not allowed unless an executable statement follows
   NULL; -- add NULL statement to avoid error
   END LOOP;  -- raises an error without the previous NULL
END;
