I'm 17 and I have them on my thighs, and boobs :( It's just a natural thing for some people's skin to do, because elasticity varies.
There are several creams/lotions out there, but most of them either don't work at all, or take years for any noticeable results.
I've only heard a few comments about my stretch marks (from close personal friends,) it was nothing bad, just a simple " Oh, you have stretch marks too?" and then we compare lol So, most people don't really pay much attention to them, probably because most if not all, have stretch marks of their own.
I still rock bikini's and daisy dukes; if you don't let them bother you, they surely won't bother anyone else :D
Perfectly normal. I had stretchmarks on the sides of my torso and inner thighs when I was in high school. Without giving them special attention or putting anything on them they have pretty much disappeared now.
i asked a bunch of my close guy friends if they noticed stretchmarks. they said that they usually don't even notice them until the girl points them out. and when they do notice them, it isn't a problem, its natural. then you got the occasional douche who has the highest standards known to man. if you run into the douche, don't listen to a word he says.
