It's worth keeping in mind, generally we have a much wider chest than your average GG. The 2" difference between our breast tissue and band size has to go a lot further. Like you, I look in the mirror and tape measure but I do not see much in changes. But I can sure feel them in my hands.
Sex, its what's on your drivers license.
Gender, its how you feel inside.
