How to be more comfortable with your naked body?

Katie
I'm really, really trying to love my body more...but I just feel so insecure about it! I have been eating right and working out and still struggling to see any changes. I have certain parts I love (face, smile, eyes, legs, ass) but am very uncomfortable with my stomach:( and my boobs, although they are fine, are on the smaller side, which makes my stomach feel all the bigger. When I'm getting intimate with my new boyfriend, if he doesn't try to take all my clothes off I usually just leave my top on because I hate it that much. And if when he invited me to shower with him after sex, I honestly didn't want to for feeling so insecure about my naked body. Believe me, I am really trying to be more comfortable with it, but comments from guys I have been with in the past make me so insecure. Help and suggestions? Thanks!!
