I wouldn't worry about it. My right inner labia is twice as long as my left and can be stretched pretty far as well. I quite like it though and wish the other was the same. But you know what, I am learning to love my body as it is and you should too. And trust me, men don't care. My partner enjoys playing with them when he is stressed, kind of like stress balls ;).
I encourage you to grab a mirror and explore your nether regions. With time you will come to enjoy them and be comfortable with them.
(PS - My labia was the same size and small until I was like 15 or 16, so things do change down there quite often.)
Some women just have large labia, there really is nothing you can do about it other than a labiaplasty.
