Vaginal discharge

Okay so.. I feel like I have A LOT of discharge. And I hate it! It will collect in my underwear through out the day and it makes me feel so gross unless I just had a shower. I do have a boyfriend and we do have sex. But half the time I don't want him to touch me down there bc I feel so gross from having discharge through out the day. And it will develop a smell. I'm not on birth control. Can anyone please tell me how to fix this or how to help it?
