I'm 5' 5" 100lbs with a 32-A chest.
I was a late-bloomer, flat as flat can be until the summer between 8th and 9th grade when I gained 20lbs, four inches, and I popped a tiny bit of curve. A year later, I started my period and my body fleshed out to pretty much current status. My waist and hips gained one and two inches, respectively, since coming to college, but that's about it.
I was constantly teased about my small breasts all through public school, by enemies, friends, and my family. I bought B cup bras for a few years because I wanted desperately to think my breasts were bigger than they were. I did the whole padded bra thing... I stopped wearing swim suits, I avoided tight shirts... anything to hide my body. Even though I was thin, I hated the way I looked. Other girls, no, grown women would say things like "I hate you, you're so thin" or they would watch me eat whatever I wanted and tell me, all the time, "I hate you."
I hated myself.
I broke free of that mind-set, and while I'm not 100% comfortable with my body, things are better.
I have a best friend who never insults my body (whereas, previously, my friends took vendictive pleasure in making me feel guilty for my weight, or shame for my lack of breasts)
I have a boyfriend who constantly praises my body. He especially loves my breasts, he think they are perfect. I tell him, at least one of us likes them.
...but maybe I'm starting to be a little fond of them, too.
My breasts are perky, they never sag, and they fit neatly in my hand. The nipples are round and centered. Because my breasts aren't big, they don't hurt if I run or do sports. I don't have back problems because of my boobs.
Maybe I can love these breasts of mine ... eventually
