Pretty unambiguously dominant. I don't identify as a Dom, exclusively, and can quite enjoy playing with my wife or lover as equals ... but if there is a power exchange (as there often is) I am definitely not giving any up. That doesn't always mean being rough or violent, either ... sometimes it's as simple as giving instructions and expecting obedience, or taking on a teaching kind of role, or just being in control, or creating a certain kind of desire only to refuse fulfillment of that same desire .... it's as much about emotional control as physical for me.
But, of course, that very often leads to some violent, abusive, bruise-inducing fucking. ~smile~
Very submissive 99% of the time. The 1% of the time I am not happens because I understand subspace so well that I know exactly what's going on in her mind (or, at least, I think I do!), which can also be a turn-on.
I walk a middle path; but I do lean more dom than sub and I could probably fill the role of a dom, in a relationship, if the need or desire was there; but I would make a very lame sub. I am way too willful, and I am not very bashful at all; and while I don't mind pleasing, I would not be content doing that alone.
