Yeast infection ??

i recently started sleeping with someone new. we were both tested before sleeping with eachother and results negative for everything.

now i have a terrible yeast infection and sores that the doctor said looks like infected hair follicles. has anyone had this?

this has happened to me after having sex for the first time. it was a yeast infection. sometimes new objects in the vagina can throw the balance of things off.

thank you!!! ive been driving myself crazy. i think it was caused by an allergic reaction to some sort of irritant maybe the soap he used because i took benadryl last night and now its completely gone. thank god. thanks for the response!!!
