Yes, I prefer it that way. Why, I'm not really sure, never thought about it. Maybe there's less to lose when someone else sticks their neck out first. But maybe it also has to do with the traditional stereotype that men don't like being in relationships. So maybe subconsciously women believe that if they (men) say these things first, or initiate a relationship first, that makes them sincere about their feelings, and not pressured into something.
But I've also read that men fall in love faster because they are much more visual than women. It's supposed to also have something to do with the fact that, women traditionally depended on men to take care of them financially, be the head of the household, etc., so they tended to be a lot pickier. If the only criteria is whether they look good, have good genes to pass on and turn your crank... makes it a little easier.
