My username finally came true...

I was worried it might one day happen. And the other day, it finally did. I queefed on my training partner. He was in my closed guard, so even if he didn't hear it, he could easily have felt it (this was in no gi). I don't know if they noticed, but I noticed. And I'm not about to forget. Should I just pretend it didn't happen, if (when) it happens again? What if they undeniably notice the queef?? Should I explain that it isn't a fart???

This can't be THAT uncommon, with all of the inversions and the stacking. So, what do you do when you, or somebody else, queefs on the mats?
