In this day and age, if you're a woman, it seems you're not supposed to want your man to have any sort of control over you. If you do it implies, for some reason, that you're weak or misguided. That somehow wanting a dominant man automatically says that you can't stand up for yourself.
So one of the (minor) thrills I get when my husband takes me in hand is a little shiver of illicit pleasure. After all, what would any of my friends and relatives think—all of whom see me as a strong woman (well, that's what they've said)—if they knew my husband spanked me because I was being too bratty? Most of our immediate family know that my husband has taken on a more traditional role as head of household, but I don't think they realise what he meant when he told them!
It goes far deeper than that, though. I don't appear to be especially wired to get hooked on illicit pleasures in general—I'm too nervous of being found out!
There is the thrill of the fight in it for me at times—the struggle to not give in, be it a mental or physical struggle; and the thrill of being overcome both mentally and physically. There is something intensely arousing in being beaten (not in the abusive sense!) despite myself, although I suspect there has to be a strong connection there already. In other words, if someone who wasn't my husband did it, I might accord them more respect as a result, but would probably not be aroused. Although I may then have a need for my husband to do likewise to me!
Then there's power—definitely an aphrodisiac for me—at least when the man I love is wielding it over me! It's not just that he has an aura of dominance, it's also that he exudes sheer certainty that he's going to get what he wants (be it sex on demand or a cup of coffee...). I may put up some resistance (well, maybe not in the case of coffee), but we both know that he's going to get his way.
But—I don't think any of this would affect even slightly if I wasn't very, very aware of how much he loves me, and if I didn't love him back at least as much.
