Vaginal irritation

Laura • Student going for career change and hoping to keep better track of my personal health :)
Hello! I really have no one to talk about these things... Um past couple days my vagina is irritated and it hurts to put 2 fingers in when I normally can put up to 3 without problems.  Also, the texture feels weird inside, like too bumpy... I'm also a virgin, so no std...
Did I contract something or is this poor vaginal care?
