You have questions. I have answers. Jon asks:

Which aspect is more central to the identity of a dominant woman, her dominance or her sexuality?

Gah! I have to choose?! As though I could give one or the other up? Hardly—at this point, they are inextricably intertwined, at least for me. (They weren't always. I had a strong sexuality long before I realized I was dominant, and during that time I never felt like I was missing anything.)

I suppose for some women, dominance alone would be enough. And I suppose for others, dominance doesn't always come along for the ride when they think about sex. But for me, the dominance is very sexual, and most of the time when I think about sex, there's a distinct element of dominance involved. So I guess if I really had to choose, sex would come first with dominance a very close second.

And if the dominant woman puts dominance first, which aspect of D/s is the most satisfying -- bondage? pain? service?

Again, it's specific to the individual woman. For me? Pain. Always pain. The inflicting of pain. And the delicious pain noises. And the bruises, and the welts, and sometimes even the blood. Oh, and the tears, too. I adore the tears.

If you were on a desert island and could have just one companion, would it be a slave/masochist (but female)? or a male (but vanilla)?

Duh, a vanilla male. First off, because I love cock. And second, because I have the pussy, so I make the rules. We're alone on a desert island, so... Boy wants pussy? Boy does what I tell him to do. (Yes, I know it's unfair. You can tell me all about how unfair it is. I will gloatingly enjoy every minute while you rant and rail and finally whine about the unfairness of it all, and then do you know what I'll say? Tough titties!)
