Stretch marks and how to treat them?

CurlyGirly2
So, I am a very athletic person and I stay in shape, but I have recently started to get stretch marks on my outer thighs, inner thigh, and outer butt. I haven't experienced major weight gain, so I don't know why it is from. I looked it up and it said it is normal when going through puberty but I didn't gain any weight at all. I have started to put moisturizer lotion on it to help, but I don't know if it actually will.

Can I get some ladies opinions on why I have them and how to get ride of them. Also right now they are quite purplish and very noticeable and I am black and white so they look really awkward against my tan skin. Will they eventually get less noticeable and closer to my skin tone?

Also if there are any guys reading this, are stretch marks unattractive? Is it like a turn off then they are pretty visible?
