Nah, just my own nature.
One of my best friends was married for 10 years to a good guy. Decent income, minor hobby in woodworking (big plus in my book), not a slob, not a bit of meanness in him. But capable of neither aggressiveness nor decisiveness. Bad as it makes me look to say this, I saw that divorce coming and wouldn't want him, either. A woman (well, *I*) don't mind a sign that a man is capable of falling a few levels on the evolutionary chain if a situation calls for it.
I know what you mean. A man can not truly be gentle if he doesn't have the capacity to be more coarse. Gentleness in a man can be admired by women (and often is), but usually when it is part of that range, and not if his range is limited to 'gentle----less gentle.' :-)
