I read an interesting article about breasts sizes and cup sizes. many guys use cup sizes in the physical descriptions, but the article said a cup size is not actually a good measurement of size by itself. It is a RATIO. An A cup is 1 inch more than the rib area under the cup. B is +2, c is +3....so a girl with a 38b is grapefruit sized breast cups and a 30b is lemon sized, so listing b cups in their physical description doesn't help a lot... it said the fruit scale is the most accurate description of a breast cup size...plum, lemon, orange, grapefruit cantelope, honeydew...
Saying all that... there is much more to a girl than breast sizes. But i found this educational.
I personally prefer the smaller fruits.
