Small Boobs And Implants

Ok so I'm all for body positivety and I think all boobs are beautiful! I loooove boobs like I love them they're soft, perfect, beautiful but for some reason I can't accept my own. I'm basically an A but I still have trouble filling out some typical A cups. People who have seen them tell me they're beautiful or cute. My boyfriend right now even told me "I usually love big titties but I love yours!!!" Which I took immediate offense to even though it was meant as a compliment 😒 I've been giving serious thought about getting implants, maybe a C Cup. My boyfriend (future husband hopefully) is really against this bc he likes me the way I am but no matter how many compliments I get on them, the thought of not being good enough until I get implants stays in my head. Has anyone had these thoughts or actually gone through with the surgery? Words of wisdom please?
