honestly grrrl, many guys don't even care about shit like that. they'd probably just be glad that you're nude in front of them.
Exactly.
Say a cougar maulled you and they're scars? That's badass
A jaguar is more exotic.
But to the OP, stretch marks are nothing to be ashamed of. I see them on girls my age (I'm 14) and it's pretty common and not unnatractive. But if they really bother you, there are scar creams and lotions and stuff that cover them and help them fade.
