Society does not always respond very well to dominant women. We are often seen as rude, bossy, unnatural, or a challenge to be put back in our "rightful place". I loved being in a military cadet program in high school because it was the one place where my dominant side was applauded and nurtured instead of squashed. But even there, I was still usually under the authority of men who outranked me.
When I became more dominant and confident in my opinions and attitudes, people from my religious past called me hateful, rude, and inappropriate. We were raised to be sweet and accommodating, and to only ruffle feathers when we were promoting the church's ideas (which were usually decided by men). Basically the message we got was "don't think for yourself, just channel your passion into roles that WE set out for you." One man told me that I could disagree with him but only if my opinions didn't contradict scripture. And who decided what contradicted scripture? We both knew he felt that was his job.
I eventually called bullshit. Ohmigod how horrible, a woman who thinks for herself and won't do as she's told! (gasp) THE WORLD IS ENDING! GRAB YOUR DICKS, THE DOMINANT WOMEN ARE COMING TO DESTROY YOUR MASCULINITY!
Not only must I look for emotional maturity, reliability and good chemistry, but now I must also look for partners who are not turned off by the fact that I may be more dominant as a femme than they are as a masculine type. Instead of letting a man always lead and teach like I was raised, I'm not afraid to jump in and take the reigns myself. Not everyone is cool with that.
Fortunately in the kink community there are many awesome masculine types who love my dominance without overly focusing on it as a fetish. It's one of the many reasons why I don't bother with vanilla dating anymore; it would take so much work to become compatible with a vanilla guy that it doesn't seem worthwhile for me in most cases.
As with most of my writings, this may easily apply to people of other genders not mentioned here.
