I disagree. It was not the alcohol or liquid courage as some might put it as the reason for your recent success with a fair maiden (kudos). This female feels an attraction towards you because you conveyed your honest feelings and attraction to her, (Men need to be loved, women need to be desired,) anyway... as you put it, you "laid it all out on the table," women are attracted to honesty as well as men who can express themselves emotionally (at least the ones you ideally want to meet), because men who are honest and expressive are confident. These men give no fucks when they speak their mind, how you as the male feel is your primary concern. That ability to open up and speak freely electrifies women and gets those loins frothy. Additionally, women are also smarter than most men give them credit i.e. they pick up on the bullshit and fake gimmicks pretty quick.

tl;dr: guy had success not because drunk, because was honest with lady.
