Vaginal odor

I have absolutely terrible vaginal odor. It's so bad that whenever I sweat even a little bit of can smell it through my clothing! I've tried EVERYTHING and nothing seems to work! I refuse to have sex with my boyfriend unless I shower first because it just smells terrible! I have hpv and so does my boyfriend and I know that could be the cause but I want to control it and don't know what to do in order to control it. HELP PLEASE IM SO EMBARRASSED!
