I know this is probably really anal of me, but I feel like it should be said because I'm seeing it more than I ever thought possible. Nipples are not areolas (areolae..?)! (Unless all my anatomy lessons have been wrong). And to the girl who thinks her areolas are big, they perfectly normal (and your boobs are hot!) and anyone who tells you otherwise is an asshole (who probably watches too much porn to know that boobs are as varied as snowflakes).
Yeah, some people do kind of mix it up. The discerning reader does know how to interpret it correctly, though :-)
