Just so you know, you ARE normal. The labia comes in different sizes and sometimes a different color. Some are short and tight to the body, while other's sort of hang down and are a little floppy, both are normal. Remember, you have a labia minora (minimal) these are more inside of the labia majora (major) and sometimes the minora are of a different color, like a darker flesh tone than the majora.
Your right when you talk about porn tho. But it's on a screen and it's so fake and gross anyway.
You are 15 and thinking about sex and what the boy's will be thinking is normal for you. But....it's really nothing to loose sleep over. You can't control the way God made your body, including your private area's. The day will come when you meet a young man and fall head over heels in love with him, he won't care what your business area looks like, although there is nothing wrong with it now. You probably aren't ready to be intimate with a boy, but your questions and concern's are important and they are real to you. Just relax and know that you are fine and you are normal.
