The role of women in society is evolving: They're now ambitious, equal contributors in areas guys used to dominate, including school, sports, work, and politics. With that change comes a new definition of what makes a man hot."

Got your attention? They go on to suggest 21st century turn-ons for guys to try out on Valentine's Day and everyday. Corporate marketing types and designers would do well to listen. Ah, first off, forget the chocolate and the lingerie. Not good.

Phone companies searching for a chance to win points with everyone should offer up a girlfriend plan with, say, a reminder to send that midday message…or packages of girl-friendly ringtones and songs he can pick through and deliver to her inbox, just to let her know she's on his mind. "

Girls are traditionally the social planners, from organizing a big vacation to making a simple dinner date with friends. If How can marketers benefit? By helping our men along.
