Boyfriend keeps making comments about my small butt?

So I've been with my boyfriend for almost a year now and things have been well, he shows that he truly loves me however he can be really insensitive sometimes. Recently he made a remark like "Your butt is small... but its okay", not too long ago while we were cuddling and he was touching it, and again recently saying "Your butt is very small... but i like it". These comments hurt me since I'm already insecure as it is and I know he loves big butts, he's told me himself. Am I overreacting/being too sensitive or do I have a right to feel this way?
