I'm only 15, about 140 pounds, and around 5 foot 8. I have what I think are stretch marks on my inner thighs..

and on my butt. Is this normal? Why do I have these? They are reddish lines that look like scars from a scratch.

Yes, those would be stretch marks, its okay to have them, totally natural, I have them all over my bottom and my thighs too. Mine faded because I was constantly massaging them with baby oil and lotions and cocoa butter. That's the trick to getting rid of them, use baby oil at night and rub it on them, then during the day use cocoa butter if you can or any lotion will work. It will take a few weeks or months for them to fade all the way, but i swear they will...
