I'm in my early 30s but old-fashioned and if a guy asks me out, I would expect him to make suggestions regarding day and activity, rather than saying "It's up to you".
Most Helpful Guy
Well I would say, it comes down to a couple of things.
1. Depending on the woman, they either expect you (the guy) to be extremely decisive in the whole decision process. So you're expected to say let's meet up, drinks at x at time y. Some women like that decisiveness others think it's pushy/overbearing/classic male dominance which they're not interested in.
2. While the point you made about women preparing themselves for date's is likely true, guys are also generally expected to foot the bill (this requires time investment, potentially stress investment from work, or potential negation of money due to having to dedicate time to this rather than work [although no person male or female should be detracting from their work for someone they're just starting to date]), they're also expected to be equally as well presented as the woman (shave/trim/shower/be well dressed etc.), and you finally you could also argue that men are expected to be in shape as well - not necessarily built like a body builder but certainly to be taking care of themselves which also requires time/effort/resources just like it does for women so I would say this is a nullified field for both sexes.
3. Sometimes, we want the woman to show she's actively interested in time investment in this, just like we're almost always expected to. I would rarely make a comment that could sound sexist, but unfortunately most women I know/have dated think that by the divine grace of them showing up we should be thankful and invest a certain effort for them to be around us. While ya that should be expected of both sexes, my view - and likely the view of most males - is that this expectation is more biased from the women's side towards us.
4. There are plenty of times where either gender will feign interest in something so the person planning the date caters to that interest (a favorite time of alcohol etc.) only for the other person to actually hate it. Unfortunately this is again, only from my experience, way0
