oral sex and yeast infections?

[starkisses18]

i am 22 years old and have been engaging in sexual acts with another girl. we have slept together 4 times over the time span of 8 months and i have developed a yeast infection twice soon after, just before my next period (the 1st and the 3rd time). are my relations with her affecting/ causing these infections? also, how long after treating should i wait to be with her again? is it harmful to her to have oral sex?

I would ask your doctor all of this.. he/she would know a lot better.
