While I've spent over 30 years as a Dom / Master to 5 different sub females, and always loved my role. I think at this stage in my life, that a Switch would be my perfect match, with a strict Mistress second, and a sub a close 3rd. The reason for this is that what started as a ***age fantasy, to be a sex slave to an older Dominant married female, has evolved over the years into my oldest and biggest obsession, to be controlled by a Dom Female, and finally experience a real spanking / whipping, along with everything else that would please my Mistress. This is the biggest item left on my bucket list.
