I've always been on the small side. I hated it. In school I wanted big boobs like all the other girls. The boys teased me mercilessly and the girls were worse. I'm a 32AA. I'm also about 100 pounds so I'd look funny with DDs.
I hated my body for decades. Now, not so much. At 51 it's great to not have to wear a bra. It's great that they aren't sagging. It's great I don't get back pain from them.
Women have long been womens' worst enemy, buying into patriacrhial standards and gatekeeping. I'm over it. And yes, small boobs are still boobs.
