As we pass the halfway mark of 2016, it’s time to look back at the collected data from 2015 to see the year more clearly. Throughout 2015 there were plenty of headlines about sex and sexuality, but what did we really learn? We’ve brought together some of the most interesting sex stories from 2015 to see how far our understanding of sex and sexuality has come.

Female Viagra Was a Big Ol’ Bomb

When Viagra was introduced for men, it not only changed the way drugs were marketed, it changed the way men dealt with their sexual performance. In the first month, more than half a million prescriptions were written for the drug and, since then, the search has been on for Female Viagra. In 2015, one company thought they had finally gotten it right and they released Addyi. The drug was meant to boost the female sex drive and essentially act in the same way Viagra does for men. The only problem was that it didn’t come close. In clinical studies, Addyi didn’t work much better than a placebo and when it was cleared to be given to people it had to include a Black Box Warning – the most severe warning a drug can offer. Potential side effects included everything from mild sweating or dizziness to menstrual spotting, weight gain, vertigo and anxiety. In the end, Addyi never met the expectations the industry had for it and it’s now no longer in production.

Porn Addiction Isn’t an Addiction

Addiction in general is a hot topic. Medical experts and laypeople alike are struggling to understand how addiction works and how it can drive people to overindulge in everything from chocolate and caffeine to hardcore drugs. For years, people have maintained that sex and pornography can be an addiction, driving people to disturbing extremes. But it turns out studies have shown that the brain doesn’t react to pornography in the same way it reacts to drugs so calling it an addiction may be an exaggeration. That doesn’t mean there aren’t people who truly struggle with their feelings and actions when it comes to sex and pornography, just that they need treatment and support tailored for that problem – not the same approaches people use to treat traditional forms of addiction.

Women Don’t Want Giant Dicks

For years, conventional wisdom said that women wanted their partners to be well-endowed. But several studies have now shown that women actually want something a bit more middle of the road. One of the most landmark headlines came out of a study published in the journal PLoS ONE. The study found that women preferred penises that were right around the national average. In the end, women opted for a penis that was roughly 6 inches long and 5 inches in girth which is right around what most guys have anyway.

Millennials Aren’t Sex Crazed

Millennials have often been dubbed the “hookup generation” thanks o apps like Tinder and a proliferation of casual sex sites. But a study conducted by the CDC found that young people aren’t actually hooking up in record numbers. As a matter of fact, it turns out that this newest generation of sexually active Americans are actually the least sexually active generation in decades. When they do have sex, it’s with fewer partners suggesting there is a bigger emotional component than people have thought in the past. Some people suggest it could be that this younger generation is more disconnected, preferring to interact online as opposed to in person. Others suggest it’s a reaction to STD scares. Whatever the reason, the end result is a generation who may be less sexually active than just about anyone since 1927.
