insecurity

I've never posted on here before but I'd really appreciate some advice from the community. My boyfriend is a very skinny guy which makes me feel self conscious about my weight and how I look. I keep wondering if we look good together and I get super uncomfortable when he hugs me sometimes because im a bit thicker than him. It's also difficult to feel good while having sex because I am so concerned with him being grossed out by my tummy. I've been trying to lose weight but it just takes so long.
