Men make more searches asking how to make their penises bigger than how to tune a guitar, make an omelet or change a tire. Men’s top Googled concern about steroids is whether taking them might make their penis smaller. Men’s top Googled question related to how their body or mind changed as they aged was whether their penis got smaller.

Do women care about penis size? Rarely, according to Google searches. For every search women make about a partner’s phallus, men make roughly 170 searches about their own.

TRUE, on the rare occasions women do express concerns about a partner’s penis, it is frequently about its size, but not necessarily that it is small. More than 40 percent of complaints about a partner’s penis size is that it is too big. “Pain” is the most Googled word used in searches with the phrase “___ during sex.” (“Bleeding,” “peeing,” “crying” and “farting” round out the top five.)

On Google, there are five and a half times more complaints about an unmarried partner not wanting sex than an unmarried partner refusing to text back. There are more complaints that a boyfriend “won’t have sex” than that a “girlfriend” won’t. Complaints about “husbands” and “wives” are roughly equal.

Another major sexual concern is climaxing prematurely. Men’s second-most-common sex question is how to make their sexual encounters longer.

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.

Women, like men, have questions about their genitals. In fact, they have nearly as many questions about their vaginas as men have about their penises. Women’s worries about their vaginas are often health-related. But at least 30 percent of their questions take up other concerns. Women want to know how to shave it, tighten it and make it taste better. A strikingly common concern is how to improve its odor.

Women are most frequently concerned that their vaginas smell like fish, followed by vinegar, onions, ammonia, garlic, cheese, body odor, urine, bread, bleach, feces, sweat, metal, feet, garbage and rotten meat.

Men make roughly the same number of searches about a girlfriend’s vagina as women do about a boyfriend’s penis.

When men do search about a partner’s vagina, it is usually to complain about what women worry about most: the odor. Mostly, men are trying to figure out how to tell a woman about a bad odor without hurting her feelings. Sometimes, however, men’s questions about the odor reveal their own insecurities. Men occasionally ask for ways to use the smell to detect cheating — if it smells like condoms, for example, or another man’s semen.

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.
