Lol 123Concerned, just like kissing will not make the lips on your face larger, masturbation will not make your labia larger.
You are normal. Women have all shapes, sizes and colors labia, small, large, long, wrinkled, smooth, hanging out, peeking out, totally hidden, uneven, white, whine red, purple, pink, almost black, dark brown and unevenly colored. During arousal, your labia will also engorge with blood, get bigger, open up a bit and it will change color when you orgasm. After that it will return to your normal look.
So don''t worry.
Take care!
