Okay so about a week and a half ago, I noticed a cut right in the crease of my,vagina where,my,lips start to meet.. And it stings to touch it, it itches like crazy and doesn t want to heal. I have applied antibiotic ointment, a&d ointment and even,tried my daughters diaper rash cream.. Nothing seems to,work. I have tried going without,underwear to help air get to it.. And it still doesn t seem,to be healing... Should I be,concerned with a std or is it just hard,to heal where it s in a moist area?
