Curious...

I've been to the doctor's before and they said it was fine but I just can get over the thought. Before my period it's like I get a yeast infection on steroids! My vagina itches and it smells off and it's a very white discharge and I was told it's fine and to use monastat if needed just to ease the itching and it works but my boyfriend likes to comments on it and even when I level back out like after my period and during my ovulation period he won't even have sex with me without immediately jumping in the shower or walking away. I know he doesn't like the wet feeling but the jokes he makes and then they disgusted way he walked away after makes me feel disgusting.... Any thoughts so I can get this under control... It's gotten out of hand.
