You say your health issues have triggered body image issues.
There are people I know who have colostomy bags who have fabulous sex lives. I know a lot of GI and GU issues can cause disturbances in body image, but I assure you, there are lots of people who are tender and understanding.
As for having a perfect body, I'd love to meet the person who has one. (Really, I'd LOVE to see that.
) I can tell you due to my own medical issues, I have some huge surgical scars. You know what most people say? "Neat."
Love is a lot deeper than a pair of size 6 jeans. I can't advise you in your marriage, but you deserve to have your body image under control.
