I just recently became aware of this sort of thing, actually. In private, I don't really mind if I go shirtless or not. In public, whole different story. Even wearing a t-shirt leaves me feeling oddly exposed. It takes a couple of layers before I feel proper. I'm not one of those ultra-conservative prude chicks, but without the whole bra thing, it feels...off.
Other fun fact: I'm not planning on getting a boob job. :cheeky: If family heritage is any indication, the hormones will make me plenty stacked all on their own.
