I'm hopelessly attracted to aggressive competitive and intelligent men

In my (30f) work life I'm a modern woman, competent and accomplished. I've enjoyed playing in the lifestyle in the past as hubby was never one to draw a line in my extra curricular activities.

Something in me is changing as I reach an age where my mind wanderers to having kids. I'm far more attracted to traditional aggressive male behavior. I'm even having intense cnc fantasies and desires.

Hubby has always been sweet and vanilla and the occasional bull has allowed me to indulge my submissive side. Now I'm drawn to men who have purpose and drive to possess me. Is this a hormone thing?
