Why would some males not want to pay, if they want the date?
Uh, if you go out and you make more(esp significantly) more than the other person, why would you not be willing to SPLIT or *GasP* pay teh whole thing?
And based on my experience, women often want the date as much as the man. That's why splitting the bill makes the most sense at first. It protects both man and woman from getting used for free drinks/dinner.
Simply making a point, and no man on this thread has said they request women to split the cost of a date. You're welcome to go off on an imaginary tangent though if it makes you feel better.
