Self conscious

Hi ladies, ive been married to my husband for a little over 3 yrs now. I've never been comfortable with my body to begin with and ive gained about 30 ilbs since we married which im trying my best to loose but im still very self conscious especially during intimate times. he says doesnt care that he is still is very much attracted to me and loves me and enjoys seeing my body but i dont feel the same way. I feel like i might gross him out or something in my mind. Any of you have this problem? :/
