burning of the vulva and vagina during sex.

mariah

so I'm tired of this, I need to figure out why this is happening. not every time, but fairly often any sort of contact with that area by my boyfriend burns. whether his hand or mouth or penis, it burns. sometimes lube makes the burning stop, sometimes it doesn't. today was the worst, i almost had to stop. no stds, i know for a fact. i don't think i have a yeast infection, but i don't know for sure. today i had a larger amount than normal of opaque white discharge. we've been using the same brand of lube, and condoms. no change in laundry detergent or the feminine hygeine soap i use for that area. we haven't been having extra activity lately, not allergic to anything we're using. i don't know what the problem is.
