Do các ông cứ quấy rối chứ sao

người Mỹ ngày càng làm tình ít hơn, và các nhà nghiên cứu muốn tìm hiểu lý do vì sao... :)

One of the most comprehensive (toàn diện) sex studies to date — the National Survey of Sexual Health and Behavior — found evidence of declines in all types of partnered sexual activity in the U.S. Over the course of the study from 2009 to 2018, those surveyed reported declines in penile-vaginal intercourse (giao hợp), anal sex and partnered masturbation.

...While today’s adolescents (thanh thiếu niên) are armed with more language — for instance, they’re more likely to express their gender pronouns and sexual identity — overall they are delayed in a number of things, including sexual expression, says Debby Herbenick, who also teaches at the University of Indiana Bloomington.

"People who study adolescence and adulthood (tuổi khôn lớn, tuổi trưởng thành), many of us have seen an overall delay, right?” she says. “Like teenagers are taking longer now to get their first driver's license. So it's not even just about sex. Like there's not as much drinking alcohol."

...Another reason for the decline in sex: People are becoming more open talking about their sexuality and how much — or how little — sex they’re having. Herbenick says this is new for our culture.

In her classrooms, she says she has seen more college-aged students openly expressing their sexuality outside of the binary of gay or straight. A growing number of people are also openly identifying as asexual, which means having little or no sexual desire.

“With greater comfort in connecting to asexual identities, there is a small, but still meaningful percent of people then who can also feel some comfort in asserting, ‘I'm not interested actually in partnered sex,’ ” Herbenick says.

On the other side of that coin, one finding Herbenick is especially interested in exploring is the increase in rough sex. In this latest study, a significant number of those ages 18 to 29 have reported experiencing things like punching and choking during intimate activity. This is happening to many young people during their earliest sexual experiences, she says.
