Confirmed: Casual sex doesn’t kill chances of a long-term relationship

University of Iowa researchers analyzed relationship surveys and found that average relationship quality was higher for people who took it slowly than for those who became sexually involved in “hook-ups,” casual dating, or “friends with benefits” relationships.

However, having sex early on wasn’t the reason for this disparity, according to UI sociologist Anthony Paik. When he factored out people who weren’t interested in getting serious, he found that those who became sexually involved as friends or acquaintances and were open to a serious relationship were just as happy as those who dated but delayed having sex.
