my vagina is slightly sore, and a little bit itchy, why?

[AshleyNicholas]

for the past, i'd say week now, my vagina has been a little bit sore, and kind of itchy (i'm talking about the actual vagina here, the hole, not the parts around it) and i was wondering what it's from. there isn't any unusual discharge, i'm a virgin so there's no possibility of it being an STD, just wondering if there's any solutions, should i go to the gyno? i'm only 16, never been to one before, kinda scary if you ask me.
