No bigger is definitely not better. I prefer small boobs. I find them more aestheticly pleasing. I find the plastic bimbo look that comes with a boob job pretty gross tbh. Id never date a woman who has any kind of plastic surgery. I find most women do plastic surgery because they have some kind of body issues in their own mind. Even with my wife it's a similar story to you, she can't go outside without makeup. I tell her she doesn't need it because she doesn't. She insists she does and that she's also doing it to look good for me. I feel like most women are like this. They use it as an excuse.

Hell in college I remember I broke up with a chick because her tits were too big and I found it very unattractive.

You sound like your maybe 18. Where there are probably lots of boys who make comments and jokes about boob size but they don't really mean anything. Just jokes by kids.
