Vagina Odor.. What's normal?

I've been recently wondering if what I've been experiencing is normal. I seem to always have an odor down there.. With or without discharge. I know some may be sweat, but it's not BO type of smell. I'm not on birth control. Im 18, sexually active (one partner, always use condoms). He's even mentioned the smell before. I shower on a daily basis, use a feminine wash.. And I just can't seem to get rid of the odor. I read stuff about yeast infections, and it scares me when I read that there should be no odor when normal (no infection). How would I know? I mean this isn't something that's been going on for a day, it's been weeks.. Months..
