So how can one month of six dates turn into an exclusive relationship? People tend to spend at least three to four hours on a good date (and that's a conservative estimate), which means after six dates (assuming no sleepovers), you've spent almost 24 hours together.
That's a lot less than six dates., a 2014 State of Dating in America survey found that 78% of singles expect to be communicated with in some way within 24 hours of a really good date, with 31% of people ages 25 to 29 citing texting as a good means of asking someone out.
In the early to mid-20th century, young daters were actually likely to keep their options open; women were discouraged from eating over a man's house during the evening, and young people were advised to date as widely as possible before getting "pinned." According to surveys from the University of California Press from 1960, 51.6% of boys in their senior year of high school went on two dates a week, while fewer than half were going steady with anyone.
Fast, but not crazy: When it comes to being "exclusive," six dates, or less than four weeks, isn't so nuts: We've had sex with the person, we've definitely spent time in their apartment and we're probably exchanging mid-afternoon texts.
The more we engage in physically intimate behaviors with our partners, from kissing to casual sex, the more likely we are to form meaningful bonds that can lead to the real-deal girlfriend or boyfriend talk.
Plus there's evidence that heightened levels of the bond-forming hormone oxytocin are responsible for driving those got-to-have-you early feelings of love as well as maintaining long-term connections.
