as for both of these terms, i would assume one would mean or go hand in hand with the other, and it's definite that a tpe means anytime(24/7), but a person who will submit to her man 24/7 may have hard limits on even some of the simplest things,

total power means just that, you have total power over a person and even though it's given freely to you, the submissive will force herself to submit to something she may not want to just since she gave that power to you.

but a 24/7 just means she's available anytime you want her, not necesarilly how you want her.

i think that might make sense? hope it does? took a lot of thinking for it to even come out coherent.
