I put off sex with my husband because I have gained weight

When it comes to having sex with my husband, I feel deeply unattractive and often put it off. He says he doesn’t mind, but I do. I am afraid my lack of interest in sex will destroy our marriage.
It can be difficult to separate body image from how we feel about ourselves. Maybe you put on the weight because you were feeling low, and are now caught in a negative loop about your body image.
