Anyone else?

Does anyone else get really irritated from wearing pantyliners? I wear them all day, everyday and I get very itchy down there and extremely annoyed. Sometimes there's even a weird smell. I don't want to go without a liner because I usually have quite a bit of discharge, to the point where my underwear are wet. I have no idea what to do. At first I was worried about an infection, but the discharge is just clear. Also, I've only ever had one sexual partner, my husband, and he's never been with anyone else. HELP!
