shoulders and narrower hips). This means that increasing the size of the penis on a taller man got them a higher rating of attractiveness than increasing the size of the penis by the same amount for a shorter man. It turns out that height and penis size matter about the same in these judgments of attractiveness. Larger penis size and taller height had almost the exact same influence on a woman’s rating of the man as attractive.
    Of course, just because penis size may factor into a woman’s judgment of how attractive someone looks does not mean that this will influence their decisions about their partners. After all, 85 percent of the women in that big survey did say they were satisfied with their partner’s penis size. Plus, an important question remains: Does penis size actually influence sexual pleasure?
    One study does suggest that penis size may make a difference for women’s orgasms. A study of 323 women investigated how often they had penile-vaginal intercourse (that means sex with a penis in the vagina), vaginal orgasms, and clitoral orgasms. (To read more about the many ways women can have orgasms, see the fun chapters on whether a woman needs her clitoris stimulated to have an orgasm and whether women have orgasms through anal sex!) The study’s whole goal was to figure out whether having sex with someone with a longer penis made you more likely to have a vaginal orgasm. According to this study, it kind of does!
    It turns out that women who prefer deeper penis stimulation are more likely to have vaginal orgasms. This was not a study that could show cause and effect. The link between long penises, deep stimulation, and vaginal orgasms could mean that a longer penis gives you more vaginal orgasms, but it also could simply mean that women who say they prefer longer penises are more likely to have vaginal orgasms. It does not mean that the longer penis is more likely to cause a vaginal orgasm, but that the women who are having those vaginal orgasms think that the longer penis might be a good thing. In this study, these women also placed less importance on noncoital sex (sex that did not involve the penis being inside the vagina). Still, this suggests that there might be a subset of women for whom penis length makes a difference in their sexual experience.
    Despite this limited evidence that size might affect some women’s experiences, having the right moves might make up for any perceived deficiencies. Sex therapists and specialists can teach you something called “Coital Alignment Technique,” which has been evaluated in a series of controlled studies. In these studies, certain positions or “ineffective” intercourse techniques are shown to cause sexual problems like women not being able to have orgasms during penile-vaginal intercourse or premature ejaculation. However, using the “Coital Alignment Technique” increases the odds of the woman having an orgasm during penile-vaginal intercourse. (In other words, these moves alone could lead to vaginal orgasms, regardless of the penis size.)
    Find yourself wondering just what this “Coital Alignment Technique” is? It sounds a little complicated, but here is what it entails: A man lies right on top of a woman, but moves himself far enough up along the woman’s body that his erection is actually pointing down, so that the top side of the penis presses against the clitoris. To thrust deeper inside, the man actually moves his body down compared to the woman, and then moves back up as he withdraws. The man and woman are supposed to focus on the movement of their pelvises and not on support or movement using their arms or legs.
    Good luck with that!
    Here’s another interesting question: Does penis size matter when it comes to men who have sex with men?
    There is not much scientific literature describing what penis size means among men who have sex with men, but one study surveying 1,065 men who have sex with men did evaluate how the men’s perception of their
