Vaginal odor

Try to make this short. I have no stds. But i am sooooo conscience about my vaginal odor. I am a pretty clean person but nothin I do helps. I don't douche but I'm tempted to cause maybe it will help. After sex it's worse, and my husband doesn't even finish in me. So I just don't know what the problem is. I don't itch. It doesn't hurt and I'm not in any pain. I also have a lot of vaginal discharge. It ruins my underwear. I have to wear pantyliners. Anyone else have this problem?
