SAM mentions that it is yet unknown how the size differences translates to behavior.
It does raise interesting questions and speculation, however. I hear plenty of women wish that her man was more emotionally available to her, and I see that a lot of men are quite emotional under the veneer of his manliness.
We might joke at our house about the "one" feeling my husband has ("Honey, let's talk about your feeling"), but both genders are complex and the pressures each person is facing deserve both of your attention.
While we might long for a deep emotional connection, what would it actually look, feel, sound and be like to have it? What behaviors might you try if your goal is connection and kindness?
