Our happy hour fact to amaze your drinking buddies with.

Not having sex for at least the first month of a relationship seems to make it stronger in the long run.

Researchers from Brigham Young University's School of Family Life interviewed 2,035 men and women who were an average age of 36 and in their first marriage. The researchers established the point when the men and women first had sex with their current partner, and then asked them questions about the strength of their relationship.

The longer a person held off on having sex before marriage, the more satisfying they reported their relationship to be. Those who waited to have sex until after marriage also reported higher levels of marital satisfaction and stability relative to those who had had sex within the first month of dating.
