I can' t say that I'm a fan of my stretch marks either and because of them, I have a hard time trying to find a swimsuit that I'm comfortable in. I'm also nervous about wearing shorts because of the stretch marks on the back of my knees. I also have stretch marks on my hips, buttocks, and my inner thighs and like you, I'm not fat either. Eventually you, me, and other girls and women around the world will just have to get over our embarrassment and just accept our flaws for what they are. In the meantime, I heard Mederma is really good for stretch marks, acne scars, burns, scars from surgeries, and scars in general. You should visit their website for more info. From looking at the prices in stores, I know that Mederma is close to $30.00. I've been wanting to try it myself but, I just haven't had the money. I hope my advice helps you out because, I know how you feel.
