Welcome to accepting your breasts JTL. It's a long road for some and quicker for others. But almost always, it seems having them, does something to those who accept them in feeling a bit more feminine than others. Not in terms of identity, but just a more in tune to the feminine side we all have, but many rarely if ever explore.
It's a beautiful thing when the breasts that grew and shouldn't have, loses the feeling of embarrassment or shame, and gains momentum in the feeling of joy and pride. Putting a bra on can be foreign for awhile, or immediately wonderful. And it's great when looking down, or in the mirror and you can feel great about how you look in a bra rather silly.
