Is it normal to feel the need to wear liners/pads every day?

I've had IC for about 10 years, but have felt the need to wear pads/liners daily since long before my diagnosis. I'm just never comfortable with just straight underwear. I'm not entirely sure why, but I'm wondering if this is an IC thing. I don't think it's due to bladder leakage, as I never feel anything leaking out. My underwear just doesn't feel "right" unless I have a pad. I've asked my PT about it and she said that it must be discharge and it's normal. However, I never really see discharge on the pad or on my underwear. The pad usually stays pretty dry. Am I a total weirdo?
