Yeah, but she said it hurts during the act, which I don't recall being the case during a yeast infection. Then again, when I have a yeast infection, I don't want anyone touching me down there so I don't know if I know what it would feel like to have sex with it. She didn't mention itching, which for me is the #1 indicator of a yeast infection.
I'm wondering if it's a bacterial infection. That happened to me once, and while I felt fine, I ended up bleeding during sex and it turned out that the walls of my hoo-hoo were all irritated and raw because of the bacteria. Didn't hurt, though.
Maybe you just need a break? Or, there are certain times of the month when you're less... um... juicy than others. However, razor blades is a pretty extreme description so yeah, you'll have to get yourself to the icky doctor and get the spatula treatment after all.
