Need Help on List of Months between Two Dates

Question

Hello everyone,
I have a table which has startdate & enddate, and need a SELECT statement to list all months between these two dates for each given ID.
I did some test, and could not figure out how to get the startdate & enddate from testing table (instead of hard code them) in the select statement.
Could anybody please help on it (Oracle 11gR2),
Thanks in advance!!!
create table testing(
id          number,
start_date  date,
end_date    date);
insert into testing values(100, to_date('05-FEB-2011', 'DD-MON-YYYY'), to_date('28-MAY-2011', 'DD-MON-YYYY'));
insert into testing values(200, to_date('20-JUN-2011', 'DD-MON-YYYY'), to_date('28-DEC-2011', 'DD-MON-YYYY'));
commit;
select * from testing;

*for testing.id = 100:*
select to_char(add_months(to_date('05-FEB-2011', 'DD-MON-YYYY'), l - 1), 'YYYY-Mon') Dates
from (select level l
       from dual
    connect by level <= months_between(trunc(to_date('28-MAY-2011', 'DD-MON-YYYY'), 'MONTH'),
                                       trunc(to_date('05-FEB-2011', 'DD-MON-YYYY'), 'MONTH')) + 1);
