Once again, the insecurities of men do not appear to match the concerns of women. There are roughly the same number of searches asking how to make a boyfriend climax more quickly as climax more slowly. In fact, the most common concern women have related to a boyfriend’s orgasm isn’t about when it happened but why it isn’t happening at all.

We do not often talk about male body insecurity. And while it is true that overall interest in personal appearance skews female, it is not as lopsided as stereotypes would suggest. According to my analysis of Google AdWords (also based on anonymous, aggregate web activity), interest in beauty and fitness is 42 percent male; weight loss is 33 percent male; and cosmetic surgery is 39 percent male. Among all searches with “how to” related to breasts, about 20 percent ask how to get rid of man breasts.

What can this new data teach us about women’s insecurities? Every year, in the United States, there are more than seven million searches looking into breast implants. Official statistics tell us that about 300,000 women go through with it annually.

Women also show a great deal of insecurity about their behinds, although many women have recently flip-flopped on what it is they don’t like about them.

In 2004, in some parts of the United States, the most common search regarding changing one’s butt was how to make it smaller. The desire to make one’s bottom bigger was overwhelmingly concentrated in areas with large black populations. Beginning in 2010, however, the desire for bigger butts grew in the rest of the United States. This interest has tripled in four years. In 2014, there were more searches asking how to make your butt bigger than smaller in every state. These days, for every five searches looking into breast implants in the United States, there is one looking into butt implants.

Does women’s growing preference for a larger behind match men’s preferences? Interestingly, yes. “Big butt porn” searches, which also used to be concentrated in black communities, have recently shot up in popularity throughout the United States.

What else do men want in a woman’s body? In the no surprise department, men show a preference for large breasts. About 12 percent of nongeneric pornographic searches are looking for big breasts. This is nearly 20 times higher than the search volume for small-breast porn.
