I had a bad case of yeast infection about 3 years ago that never came back until I started to date my current bf about 5 months ago and every time I have sex with him (with or without a condom), my yeast infection comes back. My yeast infection will go away towards the end of the week and then comes back every time after we have sex. and I shower every time after we have sex. Does anyone else experience this? Monistat is getting pricy $$$.
