Eeek...i'm probably gonna piss a lot of people off by saying this, but IMHO "submission" isn't necessarily something a sub tenders unto her Domme once and for all.

For some, it's something that is evoked in play and it's as much the top's responsibility to call that forth from you as it is yours to find it within you and offer it up.

Think back to those times when you took joy in submission: what was the context? What was happening? Maybe the two of you were doing things then that you now take for granted, or maybe you both need to ramp it up a touch.

Talk it over with your Domme. Maybe you can focus a scene around your resistance. Throw a tantrum, have her respond. Work through your petulance together.

i'm not saying some uncomfortable bondage, a gag to scream through, and a good hard spanking would solve all your problems, but then again...it just might.
