I don't go out often, but the times I do, I always manage to close girls that I've had even the slightest of sexual tension with. It just seems so much easier with alcohol.

If so, why would anyone ever go on a date to a place without alcohol (to coffee, dinner etc) if they wanted to close...?

Edit: Girls are more receptive (physical escalation is much easier), and I also second-guess myself MUCH less, putting my pretty solid game on auto-pilot.
