Kind of see both perspectives on the "who should pay" sides (some reasonable points both sides, also some pretty unreasonable both sides, but hey, glorious diversity is key to humanity).
Purely personal experience though:
Dating women, for all of them, we split it, or take turns, we've both kept (rough) track of who's paying for what, reckon we've both tried to pay for about 65% of the expenses, which means we've both felt really good about the experience overall, and that everything is fair and positive. Even had a couple where they did genuinely "forget their wallets", or in one case absent-mindedly wander off without paying at the end, and I would have absorbed it each time, but they always contacted me, of their own initiative, to pay back their share, or apologise and invite me to something to express appreciation and return the favour. Different people, so it wasn't just one woman with ethics.
Dating men, I've known a number (not all!) who have acted extremely tight or entitled to my money, or thoughtless, or inconsiderate, have "forgotten their wallets" but never thought to ask to reimburse me later, or who have demanded trifling sums (in one case 75p!!) for a "fair" split of costs. Also known men where their egos wouldn't allow them to say they didn't have any money, so they made a big show of insisting on paying (I offered to split or pay), and then asked for loans afterwards...
Anecdote, not data, but from my experience I do think attitudes are pretty different. Although I don't date straight women (obvious reasons), so possibly I'm avoiding a different set of issues that come up in that dynamic.
