White flakes coming from the inside of my vagina?

Me and my boyfriend were having , and he pulled out and we saw these white flakes all over his . I freaked out, because I knew that was coming from deep inside me. I don't know what it is at all. I thought it could be a yeast infection, but yeast infections itch, and I have no itching at all. It is a little painful during , but that was because I had a small vaginal cut inside. I was thinking that it could be something from the lubricant we were using. But I am not sure. When I had that cut inside of me, we stopped having and it just healed up. NOW, I have this white flaky stuff coming from inside of me, and it is stopping us from having sex again. I have been looking stuff up and doing research but have come up inconclusive. Anyone know what is wrong?? Please help.
