I, like you, also worried that men would reject me. I sure wouldn't. My man doesn't think my stretchmarks are pretty, but he loves me anyway, and that is all that really matters. Value your life. Don't get to the end of it and regret that you spent time dwelling on your looks.
Life is too short, so enjoy it.
I let my man know that I had stretchmarks right from the beginning. That way I new if he ran, I didn't want him anyway. Don't get me wrong, I also hope to find a cure for my strechmarks, but until I do, I am going enjoy my children, my family and my life because you never know when it will end. Besides, we'll all just end up old and wrinkled anyway and we don't take this body to heaven either.
