A new study from the University of California, Los Angeles, found that members of Gen Z want less sex in TV and movies, and instead prefer storylines that feature platonic relationships. The Onion asked young adults why they were such prudes when it came to their viewing habits, and this is what they said.
The amount of the population that is truly asexual is insanely low, and sex is biologically intended to arouse (in all senses of the word). Gotta reach the widest audience possible, and excite them when reached
While appealing to something lost people are interested in logical, the main reason I am fine with sex being less frequent in media is because it is often done so terribly as producer forced love interest crap that distracts from the media. Keep the good stuff, but drop all the bad ones.
Am gen X, disliked crappy and unnecessary sex scenes while enjoying good ones since before it was cool.
