A perfect girl should:
Be pretty, and care about how she looks. It’s the reason Playboy stays in business: men like to look at women. Even if you don’t look perfect, it should be clear that you’re trying hard.
Be simultaneously unavailable and hold the promise of a future physical relationship. That means sex on the first date is a bad idea, but if you rule it out completely, you’re probably not going to get another date from the average guy. Men are pigs, and that’s all there is to it. We want to have sex. Your dad wasn’t lying when he said that’s what we’re after. But that’s not the only thing.
