insecure/body issues

so i was never insecure about my body until a guy made fun of my nipples. i never thought they were different or off until he mentioned that they looked puffy and big, but i have a boyfriend now and we have had sex but i am scared to take my bra off because i don't want him to make fun of my nipple size or shape like my ex did.
