So my bf and I have been together for almost 2 years, he treats me like a total Queen and I know that he loves me. For some reason tho, I always get so scared that he wishes he had someone else, I know that guys are still attracted to other girls even when in a relationship but I get so sad to think what if he wishes he had her instead of me, or what if he wishes I looked like that or what if he would rather have sex with her, etc. I am very insecure and I am working on that and I do trust him and know he wouldnt cheat. And im scared to have sex and stuff because im scared that he wishes my body looked like theirs or if im not as good as one of the pornstars. I just get so sad thinking these thoughts. And I honestly feel so petty too. Advice??
