Thanks you guys!
I feel much bettter now!

Many females have them. I do, myself. I grew pretty fast in the beginning of puberty and got stretch marks on my thighs. You can try using creams, but those don't do much. Over time they will fade away some, so don't worry about it. I'm 21 and you can hardly see them now.
I have them too and it's no big deal. I assume has something to do with growing a lot in the last year.
Most people get stretch marks from just plainly growing. I have them on my leg to when I grew and my friend has them on her sides. The can't go away, but they will fade over time. If you tan a little and use lotion that may help to fade them away.
