It's interesting how many of these replies I see a little of myself in and how most of them look like the same sort of observations, from a different point of view.
The big thing I've noticed in myself is the progression. My feminine side swings from barely there to being nearly dominate in my life. This "swing" has a monthly cycle and yearly cycle. But in the last couple if years, the feminine side gets stronger and the masculine side gets weaker. I get excited as the feminine side builds, since that is more of my personality that people see. I am far more adventurous when I am feminine, and it is during these times that I am more likely to take a risk. (odd that for me, risk taking comes with the feminine side, but he is a couch potato.)
During the feminine peaks, my wife often tells me I am being too feminine, be it the way I walk, carry myself, describe something.
