Okay so my boyfriend and I have been together almost a year now and I love him very much. I feel extremely comfortable with him, but whenever we have sex I get nauseous and don't enjoy it. This is because I am always nervous about what my stomach looks like or if I look fat or something. He is a total stick, but he tells me that he loves my belly and curves. I know I shouldn't care but it makes me very very sad and uncomfortable. Any tips to help me get over this fear?
