We are both alpha types. We can snarl at one another in a heartbeat - if we get careless. Over the years we have both learned how to deal with the other without getting into a fight. Well most of the time. Even if we are fighting, we have never let it interfere with sex or spanking. That’s a whole different area for us.
Since we don’t do "faux discipline" or "DD" that may be what allows us to enjoy each other physically while still warily eyeballing the other about a perceived slight.
We will leave DD and FLR to others. We like our circumstances.
