Yes, strechmarks are a sad thing, and no they usually don't go away, for me anyway. When I was a preteen, I was very overweight, and I had developed strechmarks on my abdoman and though I've thinned out since, they still remind me of those days. And what's the worse thing about it, when ever people see it, especially my boyfriends, they all think I've been pregnate and refuse to go with me! Always stay true to yourself and never put up with stupid guys.
