sexless marriage

I'm only posting because I don't have anyone else to talk to about my situation but I've been happily married for almost 11 years and yet for the last 2 years it's been with out any kind of intimacy he has type 2 diabetes I'm 30 he's almost 40 and because of lack of intimacy my confidence as a woman is destroyed I don't want to get undressed or dressed in front of him, he's told me to get marital aids since his don't work and that has yet to do anything I've given up on having children. I don't want to leave him because I'm head over heels in love with him and have been since day one but I don't know what to do. I'm lost. I've only ever been with him. I've tried everything from new me to new outfits to weight loss and nothing works, I feel strange when he touches me because my body isn't used to that from him anymore. what do I do?? positives only please
