I voted equally horny but really it depends on the person - each individual is different, different levels of horniness, and also different in their needs for physical/emotional (I also don't believe the stereotype that for men it is purely physical, for women it's emotional...also think that for the same person it can be purely physical sometimes and emotional at other times.)
I think that books like the Mars/Venus books have done much harm in people's understanding of each other. We are all individuals, people!!!
