Some interesting tidbits about sexuality revealed.
From why we have sex in the first place, to marijuana lube for your lady parts, here’s what we learned about sex this week.
David Frederick, an assistant professor of psychology at Chapman University in Orange, Calif. wanted to look at the different ways people respond to sexual infidelity, which he defines as having sex but not falling in love, as opposed to emotional infidelity, or falling in love but not having sex. For the study, 64,000 Americans expressed via an online survey how they would respond to sexual and emotional infidelity. The participants also indicated their gender and sexual orientation (straight, bisexual, gay/ lesbian). Only one of the groups was more upset by sexual cheating than by emotional cheating. And that was…straight men! Fifty-four percent percent of heterosexual men were more upset by sexual infidelity, compared to 35 percent of heterosexual women. Sixty-five percent of straight women and 46% of straight men said they would be more upset by emotional cheating. For bisexual men and women as well lesbians and gay men, only around 30% would be more upset by sexual infidelity than emotional infidelity.
2. The mystery of why we have sex, solved at last.
As you may have noticed, humans reproduce sexually, while other species like jellyfish or plants can create offspring asexually. And for a while, scientists had a theoretical understanding of why. Fun factor aside, combining genetic information from two individuals is less efficient than doing it solo, but it’s healthier because as Jesse Hollister, a former University of Toronto post-doc fellow, puts it, “Asexual reproduction leads to a buildup of deleterious mutations over time; it’s called Muller’s Ratchet.” Of course! Muller’s Ratchet! Hollister explains, “The species’ average fitness is reduced and they are less able to compete in the ecological arena than sexual species, so they have an increased probability of extinction.”
But as any scientist knows, theories are great, but they don’t hold a candle to data. Thanks to Hollister we have empirical evidence backing the theory and the evening primrose. The evening primrose! Some evening primroses, or EPs as I like to call them, have evolved to reproduce sexually, while others reproduce asexually. In a totally incomprehensible process, Hollister and his colleagues were able to document that the EPs which produced sexually were healthier.
