my partner doesn't feel attracted to me

Miss
I love my partner.He's sweet and everything, but he just doesn't make me feel sexy at all.I feel so insecure about myself, especially since I'm an A cup and the girls he liked were bigger(I'm already an adult, but my chest is still a child...).He doesn't say anything about my outfits too...What do I do to make him notice?To feel attracted to me?
