l odor question?

I can't believe that I'm asking this as it's really embarring. But my boyfriend says that I've got l odor that's unpleasant. He makes out like I have terrible hygiene and don't care about it, but that's just not true! I wash the area with unscented, mild soap every time I get in the shower. I have treated repeatedly for BV and yeast infection thinking that might be the problem. I drink a ton of water everyday. I eat a lot of yogurt. I don't douche (never have, never will...or cleanse up in the ), and I don't have any std's. I wipe from front to back. I don't wear a lot of tight clothes. I do shave the area, but I shouldn't think that would cause a huge problem. Still, my boyfriend complains about the odor, and he acts like I'm ignorant to female problems. I'm not ignorant to the problem, but I also don't know what to do anymore. A part of me thinks he's just not fond of the way I personally smell, especially since I don't think it smells particularly bad. I have had a few infections in my life, but they're not chronic. Could it be that's just the way I smell? Could it be the lubricant we use? I'm just at a loss here!
