Why are some men attracted to powerful women?

Well DUH!

they're weak, sniveling wimps that want mama to protect them.

HOW powerful? I've found that women that excel in business and industry, make better companions. Less BS and drama, more direct and straightforward communication. They are confident. This translates to a more reactive and responsive sex partner. Often, one with some good ideas of her own. Then there is the money thing. Some of them want to pay for part of, and sometimes all the dating expenses. How is THIS not a good thing? The drive to become powerful, also makes them acutely aware of their health. They are usually more fit, healthy, and better groomed, than their more mundane sisters.

Either they are wimps or men who are very confident in their manhood and not intimidated by women that are powerful.
