To preface this, I've always had almost non-existent inner labia. it was almost like a little bit of loose skin that you could sometimes feel but it never really formed into labia persay. I've hit 18 this year and I've noticed that my inner labia have been growing. They feel bigger and slightly longer, and my girlfriend has noticed it too. Is this normal? Could they just be swollen? Would they grow past my outer labia? I'm just a little shocked and confused at the moment.
