Does Penis Size Matter? Scientists Have An Answer

It’s the question that never dies. Men and women have been debating it for years—is it the size of the wave or the motion of the ocean? Scientists think they have an answer.

According to a new study, penis size does matter … kind of. And only for some women and for certain types of orgasms. The study, published in the Journal of Sexual Medicine, found that women who have frequent vaginal orgasms are more likely to do so with men who have larger penises. The same goes for women who say they prefer penile-vaginal intercourse over other types of sex.

The study asked 323 women to recall their past sexual encounters and answer questions about how important penile-vaginal intercourse and other sex acts were to them, along with whether or not penis length affected their ability to orgasm through vaginal stimulation. They also asked the women if they were more likely to orgasm vaginally with a longer- or shorter-than-average penis. (For those of you frantically looking for measuring tape, they defined average as between 5.8 and 6.1 inches long—about the size of a U.S. dollar bill, for handy measuring purposes.)

About half (160) of the women in the study had vaginal orgasms and enough experience to compare size experiences with past partners. That’s significantly different than the oft-quoted stat that 75 percent of women don’t orgasm through intercourse alone. Of these 160 women, 60 percent actually said size made no difference, but a statistically significant number (33.8 percent) said they preferred longer-than-average size. 6.3 percent preferred partners with shorter-than-average penises.

For some researchers, this study goes into a murky area, making women feel like there is a “right” or “better” way to orgasm. “Women who orgasm through vaginal stimulation may indeed prefer longer penises, but not everyone prefers to orgasm that way,” female sexual response researcher Barry Komisaruk told LiveScience. Beverly Whipple, one of the discoverers of the G-spot, chimes in, warning against getting worked up over these findings. “To me, all of this is just so goal-oriented, and it’s difficult for me to see researchers setting up another goal [vaginal orgasm] for women to experience,” she said.

@Eric D-- I'm not moralizing about your life style, but I Loved my husband so much that if he just winked at me across a crowded room I felt butterflies. I think the chemistry between two people, if you are lucky enough to have it, has more to do with sexual satisfaction then penis size. I can't imagine sharing such intimacy with strangers, because the chemistry would not be there, nor would the trust. However, I think you are right about some of the things you said.

I believe most every heterosexual male wants nothing more than to please sexually and if he is unable to bring his partner to orgasm through vaginal intercourse this would be disappointing for him (provided she revealed that others had made her orgasm this way). If they are a couple and remain as partners the man will always feel a sense of inadequacy even if he is able to bring her to climax through clitoral stimulation. The man will always wonder what he is missing. What is sex like if he had a bigger than average penis. How would his partner react when confronted with a big penis. I am a member of an online swingers group and the thing almost all couples are seeking is a male with a thick penis. Why? because both the man and woman desire to know if it's true that a large penis is more exciting, feels better etc. and /or they already know through experience that it is. It's also partly because of the novelty and partly because for most (not all) women a thicker penis is more pleasurable (this is a documented fact particularly with women who have given birth and heavy/obese women). It's also only natural to desire something that you don't have. Personally speaking, as a man with an average appendage, I have learned to be content with the fact I won't be able to satisfy all of a partner's needs in every instance and to be content that I shared the best of the gifts I have to offer. If it turns out that is not enough for her, then so be it. It's out of my control.
