Well, it's all dependent on the type of date. If me and my swooning love are going out for a nice romantic evening and I'm all but expecting for our clothing to litter whatever room we end up deciding on, then I'm more likely going to pay for the food, gas, parking, and entertainment. Because a good wank just doesn't have the same feeling and prostitutes are more expensive if only by a little.
But if it's a casual date with a friend or a group outing to a restaurant before heading off to the movies, then everyone pays for themselves; unless it's arranged beforehand because someone is broke this week.
Honestly though, and like most of you, I don't see why it's come to be expected that men pay. It's outdated to think that women can't fend for themselves. Most of my female friends look at me like I'm crazy when I offer to pay for them anyways, so yeah, that's that.
