Been having an itchy vulva with thin, white discharge. hasn't been any odor. started when i got a new bf. current partner is not circumcised. ?

Need examination: Recommend seeing your primary care or ob/gym for an exam. Not all infections have an odor. Some causes could be candidiasis, gonorrhea, chlamydia or trichoniasis. It's best to get examined and treated. Some of these are STDs and partners will need to be treated as well.

Vulvar hygiene: The first issue is whether harsh soaps are being used on the vulva or not. Recommended soaps are Dove, Caress and Ivory. Secondly, if you wear underwear, make sure if machine washed are thoroughly rinsed of soap as itching can occur if soap is trapped in the cotton crotch and sweating reactivates the soap. Finally, boyfriend needs to wash prior to sex and under the foreskin. See a GYN MD if fails.
