What's wrong with me?

I know this is not a doctors office or anything but I'm too nervous to go to a doctor. I have a problem. A big one. And embarrassed by it. My boyfriend told me that my vagina stinks. I use SummersEve feminine wash. I rarely douche because of a infections it causes. My vagina don't itch or burn. It don't burn with I pee or have sex. I'm not sure if it's a yeast infection because I don't itch or it doesn't burn. What's wrong?
