Stretch marks?

Lili

Hi guys, I’m a 17 year old girl and I was wondering about getting stretch marks. Ok, so I’m 5’10, and I’m pretty much (I hope) done growing. I’m average weight but I have a smaller frame. I don’t have an especially large butt, and I haven’t been doing anything different (eating, exercising, etc.) to cause any shift in my butt size, but I’m getting stretch marks all over it. It doesn’t really bother me, I just want to know why they are popping up and how to stop/prevent them. Does anyone have any similar experiences or any products to recommend for stretch marks on the butt? Thanks!! :)
