Body issues

Okay so is it just me or does anyone else think that there boyfriend will not like there body. I'm not over weight or anything but I have a little tummy and I am perfectly fine with it until I think about my boyfriend not liking me the way I am. This may have things to do with past boyfriends body shaming me (they where ass holes I know) but it is always just on my mind does anyone have any advice for me to deal with this.
