I like to be dominant, but just in role play.  Some submissives want someone who really dominates their entire life. I'm strictly a bedroom role player.  It's too frick'n much work running someone else's life outside of the bedroom.

So I've only met submissives who are relatively new.  I've been rejected by submissives who have been in it a while and crave the control over their entire lives. Not for me.

So I'd say, no.  They might have had more hours under the whip, but breadth of experience, we've been either about equal or I've had a bit more.
