Do you think there's the factor of escalating too soon
I don't believe that every woman has already decided whether or not she'll sleep with you permanently on first impression or within 5 minutes.
That implies that every woman has sex on the brain 24/7 and the only thing they care about is first impressions.
But at the same time many of the girls I've gotten anywhere with seemed to like me before I did anything, maybe game has been a lie this whole time?
However it is true that you should always escalate, and that the timeline for girls who actually like you is usually pretty fast.
Escalating too fast would be if your opener was "hey I think you're pretty, let's grab a drink, what's your number?" To every random girl until you get a yes. Which is still better than being too slow about it.
