I am girl and am a tad insecure abt my breasts...read ahead?

Honestly most girls are insecure about their breasts when they are not wearing a bra. Guys legitimately love all boobs. So your boyfriend is not just being nice, he really does like them. You are just critiquing yourself because they are on you. I do the same thing, and have also been told there rather nice. They're not just being sweet, although they are, they really believe it too.
