Late to the Game, Happier in Relationships

According to a recent study published in Psychological Science,1 teenagers who wait longer to have sex experience different kinds of romantic relationships later in life compared to teens that start having sex earlier. This 15-year longitudinal study (beginning in 1994 and concluding in 2009) tracked teenagers’ sexual activity and long-term relationships into their late 20s/early 30s. Those teens that had sex before age 15 (23%) were considered “early” sexual bloomers. Most teens (60%) had sex for the first time between the ages of 15 and 19, which scientists consider normal for American teenagers (thus, “on time”), and 16% of teens reported having sex for the first time after age 19, and were labeled “late” sexual bloomers (8% of the sample did not report having sex at all in their lives).

Scientists simply didn’t have the tools or level of biological knowledge necessary to connect what happens in our bodies to how we experience the world. In the last 30 years, however, advances in genetics, physiological recording, and brain imaging have made it possible to begin to unpack some of the links between biology and psychology.
