I need advice ASAP!

So this one is a weird one! I'm 16 years old and am currently in a relationship and obviously you begin to mentally prepare yourself for that 'special' time! Well I am a virgin and I have noticed that one of my inner vaginal lips which surrounds my vaginal opening is bigger and bulbous than the other and pushes over to one side! If it's not normal I don't want to scare my boyfriend away! Shall I be worried? Thank you all! x
