Us women generally have more sensitive palates than our male counterparts. I read it in a book, so it must be true!
Otherwise, drinking beer and writing down what you think is a great way to get the thought process going. The BJCP has tons of great resources on their website - use them!
As a biologist, I can say that there is a lot of evolutionary evidence for females (of many species) having better senses for smell and taste than males. My wife's palate is one of my most important brewery guages!
From the number of responses here and from past posts, it seems that smells affects beer perception greatly, maybe even more so than taste.
Without your sense of smell all you'll get is sweet, sour, salty, bitter and umami.
During an extended period of the loss of my own sense of smell in the early 90's, I got pretty good at differentiating sweet flavors from each other as well as sour flavors. For instance I could usually tell the differences between say, fructose, maltose and other sugars, but I couldn't tell the difference between a pineapple and a strawberry in a beer. They both tasted like fructose to me. So I learned to look for color and texture differences, too.
All the actual fruit flavor comes through your nose. Pumpkin beer tastes like squash beer unless you can smell it.
