The study’s findings regarding sexual frequency declines among adolescents are particularly notable, according to Herbenick. The proportion of adolescents reporting neither solo masturbation nor partnered sexual behavior increased from 28% of young men and 49% of young women in 2009 to 43% of young men and 74% of young women in 2018.

Wow. I didn't lose my virginity til I was 18 but for about 5 years before that I whacked it all the damn time. Was I just super horny as a youngun or are teen libidos going down?
aside from the social reasons, there is a general decline in testosterone over time in the population, probably due to estrogen-like compounds from plastic.
So yeah, people are less horny. Doesn't mean they are not horny, just less.
Don't forget other factors, like stress, poor diet, reduced physical activity, and obesity. At least in the United States, all of these things are worse than ever.
