Most women are conscious that they are always at a physical disadvantage to an able-bodied man, if he chooses to use that advantage. We choose to ignore that, for the sake of our sanity, for the sake of living our daily lives, getting on with our careers, building friendships, and ultimately for the sake of our love lives. Equally, we know the fact that generally women worry about how we're seen and that we want to be seen as kind, or gentle, or at least as polite, can be used against us.
Nonetheless, on a date, 99% of the time we're the physically weaker sex and we're trusting our judgment - judgment that might be impaired by things like youth, drink, physical desire, excitement, or even wishful thinking - to keep us safe, physically and emotionally.
That's the point about strangers who date, you don't know each other. You're finding out about one another. One of the things you're finding out is whether you are looking for the same thing, whether you're tuned into one another intellectually, emotionally, physically. Reading each others body language, non-verbal cues, tone of voice, and mood is part of that.
I still read that article (with my reading influenced by the fact I see it as a single perspective rendering of a multiple perspective event) as two incompatible people date and it goes wrong because he thinks the evening is about sex and she thinks it's about connecting, and maybe even a relationship.
But that's a statistical thing - even if the number of women who were into "sex on the first date" was the same as the number of men who saw it the same way (which it isn't) you don't really know who you're meeting (in either direction). You're guessing. Which from my point of view means that the one who is at a physical disadvantage (especially if they are the doubter) needs other defences. To me, that meant regaining control of the situation - verbally if that seemed like it was enough, or by not placing myself in a situation where I felt at risk (like being alone with the person) if the danger/unknown seemed higher.
What's difficult to know as you read Grace's story is why she couldn't react in a different way - to make her reactions more explicit. Had she taken a gamble against her own instincts - the red/white wine thing, the rushed meal and trip back to the apartment? Did she continue out of paralysis, misguided politeness, optimism that he might respond, or even because she still had some vague hope that by mimicking a sexual response she might end up feeling one? I don't know. But whatever it was it did her a disservice, and that for me is the bigger picture here.
