Pansy, my experience is the opposite of yours. Estrogen brought out my female gender identity and the need to express it.
Bryony, many of your early posts influenced me to believe that I was AGP, although I prefer the less pejorative term 'cross dreamer' coined by Jack Molay. I now know that I am not.
I started on phyto-estrogen (PM), not to grow breasts, but for promised mental peace. Amazingly, I experienced relief from my GD within a couple of weeks.
I didn't know it at the time, but that was just the beginning of my journey to fully transition. Under the elevated levels of estrogen, my body and mind began a transformation. My long denied feminine identity began to emerge. I started to dress in feminine attire (I never cross dressed before that), and became excited about my developing breasts.
I experienced a growing sense of mismatch between my inner and outer presence, and as I allowed these feelings to grow, it became clear that I was a man only in the outer appearance of my body. Inside I felt alive and comfortable as a woman.
My male persona began to fade away. I began to present as a woman every chance I had. Asking for and receiving acceptance from my spouse, children, and close relatives, I am now living full-time in my authentic gender and am happier than at any time in my life.
My point is that one doesn't always know the extent of one's cross gender identity in the beginning. We, here, warn about the dangers of 'playing' with estrogenic herbs to satisfy some ill-understood craving for female breasts while intending to maintain male identity. It can reveal aspects of your psyche that you never knew existed. It can turn your life upside down, or right side up.
To all the new members at Breast Nexus, please be respectful of the power that these substances wield.
