Men were twice as likely as women to respond affirmatively, perhaps contributing to current gender stereotypes. Gay participants were more likely to as well - with gay men and women admitting to sleeping with first dates at twice the rate of their heterosexual counterparts.
So does this mean that hook-up culture is on the rise? Perhaps, but not among the most likely candidates - college students. The study showed that only 22% of those aged 18 to 24 had slept with someone on the first date, whereas older participants in age categories ranging from 25 to 54 had the highest responses at 39%.
Divorcees were also 25% more likely to have sex on the first date compared to singles.
Gina Stewart, a dating expert with DatingAdvice.com said divorced men and women weren't as interested in delaying a sexual relationship. “For divorcees, they are often people who are (perhaps) used to having sex more consistently than their single counterparts, so continuing into a new sexual relationship from date one isn’t as much of a forethought,” she said.
Answers varied according to region and income as well. Forty percent of those earning $75,000-99,000 answered affirmatively, whereas only 30% of those making under $25,000 a year said they'd had sex on a first date. People from the West were also more likely to have sex than their Midwestern counterparts, with two in five saying they had sex on the first date compared to three in ten Midwesterners.
The study surveyed 1,080 respondents over the course of three weeks. Participants were chosen to reflect the U.S. population in terms of age, gender, income, race, sexuality and other factors.
