Amber, I think you really nailed it for me with your post!
Yes, there are times I do have submissive cravings - ones I still don't understand where they came from 'cause there weren't any of the childhood or young adulthood indicators that so many here seem to have had. It's not something I went looking for or felt was lacking in my life before I stumbled into a situation where I was very clearly not in control. Denying those cravings exist, however, would be pointless self-delusion.
But to your point, it does very definitely take the right circumstances to bring those cravings to light, to put me into the frame of mind where I'm willing and even want to submit. In almost every aspect of my life, I'm very much in charge, living life on my own terms, independently. In most of my relationships, I'm the dominant partner. But with the right man & the right situation, giving myself to him can be like the coolest thing ever.
