I'm a plus size girl and there are days where I feel super sexy and days where I feel super fugly. I'm not sure why I have such varying moods, but I feel like my bf's past may be part of it. He plays sports and has only dated super fit and skinny people. He doesn't treat me bad or anything, he actually treats me like a goddess but I feel inadequate compared to his exes body wise. How can I get iver this?
