I've always been a very skinny guy. Over the summer however I've started to gain some weight and have plateued at a comfortable 172 pounds. (I'm 6'1 tall.) I just noticed something. I have huge, obvous stretch marks all over my butt. I have no idea how long they've been there, but they're all over it. Will they ever fade or disapear, or are they scars? I didn't want to be very skinny forever, but this is ridiculous. I excercise all the time, yet I now have these extremely unsightly marks all over my rear end. Is there any way to make them go away?
