Loving Your Feminine and Masculine Womanliness

I recently spoke with a good friend who said she was feeling very unfeminine and it was causing her great concern. She's attractive, has a beautiful, strong body, a good style of dress, and a powerful personality. She said her new roommate is petite and soft-spoken, and wears skirts and flowey blouses. Comparing herself to her roommate, my friend felt ungainly and clunky. She perceived her diminutive roommate as the perfect example of feminine. I asked my friend, “do you feel masculine?” “Not really,” she replied. “Just not feminine.”

Hmmmm. What is this concept of feminine?
