However, the reported preferred length of 6.4 inches is fraught with problems and is likely to of been inflated by the females in the sample as it is the most mathematically inconsistent for the following reasons: Non-bone pressed length is far too rare for there to even be a preference for it, with almost universally all of the women never experiencing it; Bone pressed length, however, fares little better, whilst being more common the majority of women could not possibly experience a penis with bone pressed length of 6.4 inches and is thus too rare for there to be a preference for it. Length seems to be more inaccurately recalled than girth (it seems like women underestimate, but according to one of the authors the opposite could be true, do not research penis size recall in women is nascent). For both Non-bone pressed as well as bone pressed lengths, the difference between the preferred length and the theoretical maximum is too small a difference to justify a woman suddenly leaving her partner on the basis of him being too large. All the mathematics point to there being an inflation in the reported preferred length in men in the sample. | However, the reported preferred length of 6.4 inches is fraught with problems and is likely to of been inflated by the females in the sample as it is the most mathematically inconsistent for the following reasons: Non-bone pressed length is far too rare for there to even be a preference for it, with almost universally all of the women never experiencing it; Bone pressed length, however, fares little better, whilst being more common the majority of women could not possibly experience a penis with bone pressed length of 6.4 inches and is thus too rare for there to be a preference for it.

On an interesting note, [https://calcsd.netlify.app/preferences CalcSD visualised the spread of the reported preferences of the above study] using the supplemental data.<ref>https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0133079</ref> On the Graph, we find that a (or at least a few) women reported a size preference from around (and I'm eyeballing here) of 8.6 inches in length and 6.5 inches in girth. Now let's note the following, there were around 75 participants on average having 6 lifetime partners; this means that collectively they've each experienced 450 men. A bone pressed penis of 8,6 inches corresponds with a greater the 99.99% percentile (4.5 SD away from average and 1.6x larger than average) whereas a non-bone pressed penis of 8,6 inches corrosponds with, an even, greater than the 99.99% percentile (5.4 SD away from average and 1.7x larger than average) and finally a girth of 6.5 inches corresponds with the 99.99% exactly.

Now, instead lets calculate the probability that, collectively, that any woman (never mind at average preference) from the study could of possibly reported these measurments given their collective sexual experience of 450 men. As a group (or the chance that at least one of the 450 had a penis of these measurments) the odds of encountering encountering a penis of length 8,6 inches is (bone pressed) 2.2% and (non-bone pressed) 0,45% and the odds of encountering a penis of girth 6,5 inches is 4.40%. As we can see, the woman/women whom reported the largest size preference out of the entire group could not of possibly had sex with the penis size preference they'd reported, even if they'd slept with all 450 of the men. | ||
Here's something peculiar, a penis of bone pressed length 7.54 inches (situated at the 99.85% percentile) and girth of 6.07 inches (also situated at the 99.85% percentile) both have about a 50% of occuring in '''at least''' one of the 450 men that all of the women have collectively experienced, yet the graph shows (although by no means even a plurality) a significant number of women stating their preference as above that; since a penis of about 7.5 inches long and 6 inches around is so rare that these women couldn't of possibly experience a man that large unless they'd slept with thousands of men (which they haven't) we can only presume that they are inflating their stated preference. The thing is they don't even have to be inflating by much. Whilst a woman has a 50% chance of encountering a man with a penis of bone pressed length 7.5 inches of sleeping with at least 450 men, she also has a 50% chance of encountering a man of bone pressed length 7 inches after sleeping with 50 men and has a 50% chance of enountering a man of bone pressed length of 6.5 inches after sleeping with 9 men. Seeing as how a mere 0.5 inches makes the difference between moderately rare, to damn near impossible to find (and this is only for bone pressed length) we must conclude that the largest size preferences reported are likely overstating their preference by at least half an inch to an inch. | Here's something peculiar, a penis of bone pressed length 7.54 inches (situated at the 99.85% percentile) and girth of 6.07 inches (also situated at the 99.85% percentile) both have about a 50% of occuring in '''at least''' one of the 450 men that all of the women have collectively experienced, yet the graph shows (although by no means even a plurality) a significant number of women stating their preference as above that; since a penis of about 7.5 inches long and 6 inches around is so rare that these women couldn't of possibly experience a man that large unless they'd slept with thousands of men (which they haven't) we can only presume that they are inflating their stated preference.

So it seems that prefered penis length will be just above or aorund 6 inches with the most dense area report either above or below that (other studies have also confirmed a 6 inch preference). Most women reporting a length | So it seems that prefered penis length will be just above or aorund 6 inches with the most dense area report either above or below that (other studies have also confirmed a 6 inch preference). Most women reporting a length preference 7 inches or longer are likely inflating actual preference as there were not enough men experienced collectively to justify the number of women reporting a preference above 7 inches. Prefered girth is likely around 5 inches although the second densest group of women reported a surprisingly low girth preference of 4 inches. All in all, most women report a preference average to slightly longer than average penis and some groups of women will report a preference for longer than average penises. Most women will report an average preference for girth; surprisingly some groups women might even prefer thinner (albeit longer) penises. | ||
Though on that note one must factor in that the women in this study were from California and that this might not neccesarilly entirely be reflective of the United States (or even most other Western Countries for that matter). For example, a series of studies done by Dixson which, among other things, had women from various countries (Specifically, the USA, New Zealand, China and Cameroon) rate the attractiveness of different penis sizes.<ref>https://www.researchgate.net/publication/6638728_Studies_of_human_physique_and_sexual_attractiveness_Sexual_preferences_of_men_and_women_in_China</ref><ref>https://www.researchgate.net/publication/23783202_Human_Physique_and_Sexual_Attractiveness_in_Men_and_Women_A_New_Zealand-US_Comparative_Study</ref><ref>https://www.researchgate.net/publication/6661420_Human_Physique_and_Sexual_Attractiveness_Sexual_Preferences_of_Men_and_Women_in_Bakossiland_Cameroon</ref> The countries with the strongest preference for larger penis sizes were (going from strongest | Though on that note one must factor in that the women in this study were from California and that this might not neccesarilly entirely be reflective of the United States (or even most other Western Countries for that matter).

Women from New Zealand rated average and slightly above average penises as the most attractive, with the largest penises being rated as less attractive than average ones. Women from Cameroon rated average and slightly below average penises as the most attractive, followed by slightly larger than average penises and they rated the largest penises as the least attractive. Women from China rated average and slightly above average penises as the most attractive but overall penis size had less of an effect on attractiveness for Chinese women. Finally women from the USA rated slightly above average penises as the most attractive followed by the largest penises then average penises; penis size had the largest effect on attractiveness for women from the USA overall. To conclude, seeing as cross-culturally women from the USA (specifically California) place the most importance on penis size and seeing as the 3D model experiment was also set in California, it seems that the preffered sizes given here might only be reflective of the liberal state of California and that women in other states and countries would probably report much smaller prefered sizes; it seems this is especially true in Asian countries were women are not as sexually liberal. | Women from New Zealand rated average and slightly above average penises as the most attractive, with the largest penises being rated as less attractive than average ones.

Whilst it is certainly true that size matters, the notion that 'bigger is better' seems to be unfounded. For example a 2012 study claimed that women who preferred larger penises had a higher rate of orgasm during penetrative sex. They argue that since a preference for a larger penis only predicted an increase in rate of orgasm during penetrative sex independent of other sexual activities, that "men with larger penises might be better lovers" and that larger penises elicit orgasm more often. However that rate of orgasm was predicted independently of other sexual activities proves nothing. Considering a 2010 study showed that the distance between the clitoris and the urethral meatus affected success in orgasm during penetrative sex, but not during masturbatory practises.<ref>https://www.researchgate.net/publication/49718166_Female_Sexual_Arousal_Genital_Anatomy_and_Orgasm_in_Intercourse</ref> Thus that Costa et. al found that penis size predicted greater incidence of orgasm from penetrative sex independent of other sexual activities means nothing until there are anatomical controls in place.<ref>https://pubmed.ncbi.nlm.nih.gov/23006745/</ref> For further discussion see The Human Penis below. | Whilst it is certainly true that size matters, the notion that 'bigger is better' seems to be unfounded.
