I'm gonna go with the flow on this one and say the instigator of the date should pay, at least the first time.
The old fashioned thing where the dude buys dinner and then depending on how expensive it was the woman owes him some amount of sexual favors, but it's all unspoken, just seems like a weird form of sexual bartering that I'd prefer not to get involved in.
But then women are kinda taught that they can't "Give it away for nothing" so the transactional nature of sex is unfortunately built into our society.
Actually I'd love to hear from some woman kiwis on their own impression of that, I wonder how widespread and how explicit that idea is. I only hear what I hear from women, and observe the limited bits of behavior I see, but I imagine women are much more conscious of this.
Like, do women feel that "giving it away" too easily in a relationship will hurt the future prospects of that relationship?
Are women conditioned to use sex as a bartering tool consciously by anyone, or is it more something that is picked up by society? Or is it just because men usually want sex more than women? Or do you reject the entire notion that women in our society use sex for bartering?
Are women more worried about being judged as a "slut" by men, other women, or does it not matter who it is doing the judging?
For example, as a man, if I were still dating, I would want to have sex as soon as the woman wanted to. I wouldn't be worried that this would adversely affect the relationship (I'd consider it a positive move for the relationship). If the woman hinted at the idea of sex as a reward for spending money on her, it would bother me, as I'd feel the relationship were cheapened, and the woman was not as interested in me as she was in what she could get from me. I would not in any way think less of the woman if she wanted to have sex right away, I wouldn't spend a moment of thought on her being a "slut" for wanting sex as much as I do.
