Hahaha. Well here's a little story! I'm a young woman and I have a cousin about the same age. I don't have a large labia by any means, but it is slightly bigger than average. My cousin, however, has a slit. She's a year younger than me, and she'd slept with over 20 men by the time she turned 17, having frequent sex with a few of them. She maintained her slit too. I however, have had two men, and only semi-frequent sex with one. Our vaginas were the same way when we were kids as they are now. Women are born with whatever labia they are born with. Hardcore porn is called hardcore because it is more detailed and more erotic. The non existent labias in soft core porn are a method of censoring, which was established when porn first came out. It's a shame that the hardcore porn has made you think of women born with larger labias as loose or immoral, because in MANY cases, the larger labias are wetter, provide more pleasure and traction for the man, and open into a tighter vagina.
Just like guys have different length foreskin so females have different size labia.
Be proud of your body as it is as guys will love them.
