"Ask your date: 'Do you like the taste of beer?'
Because: Among all our casual topics, whether someone likes the taste of beer is the single best predictor of if he or she has sex on the first date.
No matter their gender or orientation, beer-lovers are 60% more likely to be okay with sleeping with someone they've just met. Sadly, this is the only question witha meaningful correlation for women. For men there are a few others:
Predictive question/Implied odds of first-date sex
