Question

Two days after my period I developed these white bumps which have now turned into almost abscess like sores.  They go all the way down my outer labia and are around my anus as well.  I have not had unprotected sex or sex at all in over a year, and have never had symptoms like this before.  There's a terrible smell-not sure if it's something oozing from the sores or my vagina, because the sores don't appear to have opened.  They sting when touched. I don't understand what could be going on.
