i have a few little blisters on the skin between my vagina and anus (but it is more on the buttock than anything if that makes sense, NOT on my vaginal opening). i had something similar a few months ago but it was only 1 lesion - it almost looked like a popped blister. this is the second occurance and there are about 4 or 5. they look like they are fluid filled, with slight redness and a lot of pain when anything touches it. is this herpes?
