Two nights ago after going to the bathroom I noticed red, and what looked to be dry flaky skin around my vagina and to my butt, now the peeling has gone away but it's tender and red. All I can say is that a couple things may have triggered it, I had been masturbating with a vibrator in that area, and after that I noticed what's going on down there. Also the previous day I had my period, and the pad had been irritating the area as well. I'm pretty worried about what this could be though, it's uncomfortable.
