insecure 😒😒

ive been with my boyfriend for six months. ive been talking to him since april. i trust him completely im just embarrassed to let him see my boobs because i have big nipples . we have sex but i dont take my bra off. i just tell him i dont want to so he stops trying to take it off. i also dont let him eat me out cuz my skin is dark around my vagina. like the insides are pink but around my thigh nd outer lips are a dark color . i dont know if theres anyway to fix this discoloration ? im not really dark im just tan. he says he loves me and my body but im just too embarrassed.
