If you want him to find you instantly attractive, order this on your first date!
As they say, the way to a man's heart is through his stomach...
A coffee date is a classic first date option, and with Starbucks forever adding weird and wonderful options and add-ons, this might be a tough one to navigate.
As they say, women like their coffee the way they like their men, so don't go overboard with the fussiness. Ordering an 'XY with lactose-free milk - or do you even almond milk? Oh, then soy, but please unsweetened...' is just going to make you come across as high maintenance. Men love uncomplicated women, so on your first date opt for something simple, and he'll instantly think you're a cool, uncomplicated kind of girl.
