Vaginal pain

So me and my boyfriend hung out yesterday. We did some stuff, he fingered me and ate me out that was all. But before that my vagina was kind of burning and itching. I was wearing a lace thong so I thought that it might've just been rubbing my skin. But today I've been really dry,  theres a weird odor, itching more, and still burning. I have like no discharge at all but there is some white stuff in between my labias. I'm 15 and definitely don't want to tell my mom or go to the gyno! Please help!
