I have small breasts. I am just in a B cup (or could possibly even be an A on a non-hormonal day). I actually really like having small breasts, and there are some definite benefits to it. I don’t have to wear a bra all the time, and I think it would be near impossible for them to ever sag.
I remember girls saying when I was back in high school, to see whether or not your boobs are perky you put a pencil underneath them, and if it falls out, then you have perky breasts. I find it hard to imagine that high school aged girls breasts are not of the perky variety, but that’s another topic for another day. Now, I don’t believe I have an “underneath” of my breast, so I have passed the perky breast test with flying colours.
