dear butterfly!
I think I know how you're feeling.. I've been seeing my boyfriend for ten months now, and I still hate it when he looks at me. I'm kind of ashamed of my body, and I wonder what he thinks of it.. but I've learned to live with it, and trust him when he says he likes it. I know that he loves me and doesn't care how I look. And I'm sure your boyfriend feels the same. you just have to trust him when he says that he thinks you're beautiful. even though it can be difficult! if you have been going out for six months, he really must love you for who you are. If I should give you an advice, it would be to trust yourself, and love yourself for what you are..
and don't be afraid of the first time... It's really nice to do it with someone you love. It's such a special monent, that he won't even think of how you look.... the only thing on his mind will be: God, I love her!
