What do you think of women with stretch marks?

Okay I'm going to be honest here and probably embarass myself but oh well, I have really bad stretchmarks basically covering all of my stomach soo that it looks like a road map. I didnt get one throughout my entire pregnancy until the last few eeks when I dropped. Then I was covered. My son is definitely worth sacrficing my appearance for but I do get depressed abotu it sometimes, its hard being 21 and feeling like I cant wear a bikini any more because i am ashamed. I am really self conscious about it and low about it...
