I empathize with you and, while my situation was a bit different, I know the fear you are feeling. And in our society where over-sexed and surgically-enhanced women flood all forms of social media, that fear is reinforced pretty much all day long.

You said: "I'm feeling absolutely self conscious and I don't even want to have sex with my fiance because I'm ashamed of my breasts. They went from AMAZING and FULL to almost non-existent. I feel like along with the weight loss went my breasts and my womanhood. I don't even feel like a woman anymore."

He's your fiance, so I'm hoping you'll be comfortable enough with him to try this. But your feelings ARE valid because they are yours and because they are affecting you, so be candid with with him! Tell him your fears as exactly as you posted them here. Tell him you'll probably need to be reassured many times before you adjust to this major change in your life, and ask him for his support for this repeated reassurance. If he doesn't already know your feelings, this might bring him great relief (knowing clearly why you don't want to have sex with him lately)! He might be blaming himself, or wondering what he did wrong, you know? It took me years to believe that my now-husband actually prefers small-breasted women! But he doesn't mind reminding me, even now after many years, because it will usually cause me to give him some warm affection whenever he does.

The guy proposed to you. He wants to be with you through the good and the bad in life. Tell him what you need and let him be your hero. I bet it will make him happy to do it! Let us know if you have success with him!!

PS: Frederick's of Hollywood makes underwire bras and outfits that leave most of the breast exposed, while still providing support to make you look bigger and perkier. When I'm feeling particularly down on myself because of my boobs, those help me to feel sexy so I can act sexy. I hope that helps!
