It sounds like you might have weak pelvic floor muscles. Try doing pelvic floor excrcises daily which involves clenching the muscles that control the flow of urine. Do ten sets of these twice a day and see if their is any change. A weak pelvic floor can also be due to lower back problems and is also common for women who have had children. See your GP for further help and advice. :)
Please take a hand held mirror and look to see if there are any tissues bulging out of the vagina, if there are you have pelvic organ prolapse and it needs to checked for degree of severity to see what type of treatment you need. If there are no tissues bulging doing Kegels will strengthen the pelvic floor enough to help.
