    Full vinyl polysiloxane casts of the vagina were obtained from 23 Afro-American, 39 Caucasian and 15 Hispanic women in lying, sitting and standing positions. A new shape, the pumpkin seed, was found in 40% of Afro-American women, but not in Caucasians or Hispanics. Analyses of cast and introital measurements revealed: (1) posterior cast length is significantly longer, anterior cast length is significantly shorter and cast width is significantly larger in Hispanics than in the other two groups and (2) the Caucasian introitus is significantly greater than that of the Afro-American subject.

    quote:
    "The shape of the vagina also varies from woman to woman and can be categorized as parallel sides, conical, heart, slug and pumpkin seed [21,23]. When compared among races, the pumpkin seed shape was found to be specific to African-American women [23]


    To me, the most interesting data compared vaginal shapes among 23 African-American, 39 Caucasian, and 15 Hispanic women. The researchers found that the Hispanic ladies’ vaginas were wider overall, longer in the back, and shorter in the front than the vaginas of the other women. The study also noted that the Caucasian women had a much larger vaginal opening than did the African American women.

    So basically, Caucasian women tend to have longer vaginas at the front of the body (anterior), shorter at the rear. Hispanics tend to have larger overall width (what you would term tightness) with the shortest length. African women tend overall to have the smallest width (tightest).

    For some reason Asian women weren't included in the study. But from my own experience black women tend to have better grip in general because of muscle mass down there.

    Flawed research beginning with the bias number of subjects hence conclusions are unreliable.

    I agree with bush. Being forced to live with stats educated me in data points. This is not enough to make a conclusion. With this few subjects to study there are too many other factors to consider. Besides with all black dudes having humongous dicks, why would their women be tighter?

    That comment is for Cappy.

    Disclaimer: this is obviously a flawed study....
    From my interracial and homogenous dating experience, anecdotal as it may be; sex with white women tends to be a very submissive experience for them, focusing on letting the guy do his thing and not getting hurt in the process. Black and latina tend to be more "combative?" in bed, using their physicality to ensure their own satisfaction, thus the muscles used during sex tend to be better developed. Again, not any proven scientific fact, just observation.

    A consistent sample number of 30 or greater would allow for statistical validity, which only the Caucasian quantity has that. So I agree. Need more pussies

    Pumpkin seed? Slug? LOL. The article is one step above a hoax. The "research group" never published anything else. The publisher is a "family run" vanity press for quacks who need to do some quick publishing.

    No, no the study of pussies is a noble quest!
    As a scientist myself I cannot think of a more emersing, engaging, penetrative and would wish to study closely the depth of the subject ;)

    I suppose that if we wanted to extend this out to its' logical (or illogical) conclusion, we might say that the black guys with huge cocks like white women because the black pussies are too tight to get it in!:p

    The tightest pussy I've been in was a black woman - BUT - she had Vaginismus. So her pussy was REALLY tight. It had nothing to do with her being black.

    The second most iHer pussy griped my cock so heavenly! She was Vietnamese and it was fucking AWESOME!

    It's true. All these links and studies show that their vaginal canal's are smaller, the pelvic muscle strength is stronger than other races. The explanation being black women have more musculature in their PC muscles as well as their vaginal canal's being smaller due to that race naturally giving birth to babies with smaller heads than white or Asian women. Also the rates of incontinence is smallest in black women.

    Racial Differences in Pelvic Anatomy by Magnetic Resonance Imaging

    Comparison of vaginal shapes in Afro-American, caucasian and hispanic women as seen with vinyl polysiloxane casting. - PubMed - NCBI

    http://www.justanswer.com/ob-gyn/6d5...-vagina-s.html (do women with longer torsos have deeper vaginas)



    Racial Differences in the Structure and Function of the Stress Urinary Continence Mechanism

    Full vinyl polysiloxane casts of the vagina were obtained from 23 Afro-American, 39 Caucasian and 15 Hispanic women in lying, sitting and standing positions. A new shape, the pumpkin seed, was found in 40% of Afro-American women, but not in Caucasians or Hispanics. Analyses of cast and introital measurements revealed: (1) posterior cast length is significantly longer, anterior cast length is significantly shorter and cast width is significantly larger in Hispanics than in the other two groups and (2) the Caucasian introitus is significantly greater than that of the Afro-American subject.




    The pelvic inlet was wider among 178 white women than 56 African-American women (10.7±0.7 cm compared with 10.0.±0.7 cm, P<.001). The outlet was also wider (mean intertuberous diameter 12.3±1.0 cm compared with 11.8±0.9 cm, P<.001). There were no significant differences between racial groups in interspinous diameter, angle of the subpubic arch, anteroposterior conjugate, levator thickness, or levator hiatus. In addition, among women who delivered vaginally without a sphincter tear, African-American women had more pelvic floor mobility than white women. This difference was not observed among women who had sustained an obstetric sphincter tear.

    I think torso length and hip width are pretty good determiners for vagina size. It is not the height of of the women (head to foot) which determines the depth of the vagina.
    There is definitely a racial difference and also genetic factors which determine the length of vagina. White women give birth to babies with larger heads "on average" so their hips are "on average" broader, and their vaginal opening is also larger. Black women, actually have smaller vagina's. They give birth to babies with smaller heads and have smaller hips. Black women store more body fat on their buttocks, but their hips are actually smaller (men and women). White people also have longer torso's and white women also have longer vagina's. Asian women have shorter vagina's than both black and white women, have wider openings than black women, but not as large as white women. Unlike penis size, the body size/shape of a woman has an influence on vaginal size. Taller women (longer torso) with wider hips will most likely have longer and deeper set vagina. Torso size/length is more significant than actual height. As for men however, a 6' 8" man may have a smaller penis than a 5' 8" man, just like has ears may also be smaller. External organs are not influenced by body size or height, whereas internal organs are.
    Thank you

    INTRODUCTION AND HYPOTHESIS:

    Limited knowledge exists about pelvic floor muscle (PFM) function in ethnic groups. The aim of this study was to compare PFM strength and endurance in a group of black, white and mixed-race women.
    METHODS:

    This was a cross-sectional study. Maximum voluntary contraction (MVC) and endurance were measured with a perineometer and vaginal balloon sensor. Two sets of three MVC of the PFM were recorded; resting phase was 5 min. Demographic variables and factors associated with PFM strength were assessed.
    RESULTS:

    A total of 122 nulliparous black (n = 44), white (n = 44) and mixed-race (n = 34) students participated. PFM of black women were stronger than that of white (p = 0.02) or mixed-race (p < 0.01) women. The MVC of PFM in black women decreased (p = 0.02) between the first and second set of contractions.


    OBJECTIVE:

    We calculated incidence rates of urinary incontinence by incontinence frequency and type over 4 years in Asian, black, and white women in the United States.
    STUDY DESIGN:

    Prospective analyses included 76,724 participants aged 37-79 years in the Nurses' Health Study cohorts with no incontinence at baseline.
    RESULTS:

    The 4-year incidence of incontinence at least monthly was higher in white women (7.3/100 person-years) compared with Asian (5.7/100 person-years; P = .003) and black women (4.8/100 person-years; P < .001)
    . The incidence of at least weekly stress incontinence was significantly lower in black compared with white women (0.1 vs 0.8 per 100 person-years; P < .001). The difference between black and white women in the incidence of any incontinence and stress incontinence remained significant after adjusting for known risk factors (P < .001 for both).

    Objective

    To compare the structure and function of the urethral sphincter and the urethral support in nulliparous black and white women.
    Methods

    Eighteen black women (mean age 28.1 years) and 17 white women (mean age 31.3 years) completed this cross-sectional study. The following assessments were made: urethral function using multichannel cystometrics and urethral pressure profilometry, pelvic muscle strength using an instrumented speculum, urethral mobility using the cotton-swab test and perineal ultrasound, and pelvic muscle bulk using magnetic resonance imaging.
    Results

    Black women demonstrated a 29% higher average urethral closure pressure during a maximum pelvic muscle contraction (154 cm H2O versus 119 cm H2O in the white subjects; P = .008). Although not statistically significant, black women had a 14% higher maximum urethral closure .23) and pressure at rest (108 cm H2O versus 95 cm H2O; P = a 21% larger urethral volume (4818 mm3 versus 3977 mm3; P = .06). In addition, there was a 36% greater vesical neck mobility measured with the cotton-swab test (blacks 49° versus whites 36°; P = .02) and a 42% difference in ultrasonically measured vesical neck mobility during a maximum Valsalva effort (blacks = −17 mm versus whites −12 mm; P = .08).
    OBJECTIVE:

    The objective of the study was to compare levator and obturator thickness between asymptomatic black and white nulliparas using three-dimensional (3D) magnetic resonance imaging (MRI) color mapping.
    STUDY DESIGN:

    3D color-mapped MRI of pelvic muscles were evaluated in 22 similar nulliparas (12 black, 10 white). Levator and obturator (OI) were divided into right and left. Levator was subdivided into puborectalis (PR) and ileococcygeus (IC) portions. Maximal thickness of each muscle was recorded and compared between groups. Nonparametric testing was applied, with significance at P = .05.
    RESULTS:

    Levator thickness was significantly greater in blacks bilaterally (median right PR, 8.5 vs 6.0 mm; P = .001; right IC, 6.5 vs 4.5 mm; P = .002; left PR, 9.5 vs 5.75 mm; P = .0002; left IC, 6.5 vs 5.75 mm; P = .02). Obturator thicknesses were similar (right OI, 20.0 vs 19.5 mm; left OI, 19.25 vs 19.25 mm; P = NS).
    CONCLUSION:

    Significantly thicker levators but similar obturators were seen in black nulliparas, compared with white nulliparas. These levator differences may influence pelvic floor dysfunction risk. The clinical significance of these findings is under study.







    So overall what all these studies by the Journal of Gynecology and Obstetrics show is that black women have smaller vaginal canal's, more muscles in their vagina, and overall the strongest pc muscles between all the races.

    AKA smallest, tightest, strongest

    And this is before and after having kids as well

    I am not going to argue with those above quoted finding based on good science however as a scientist myself require validation by performing my own physical research in order to substantiate/refute the published claims.
    Therefore already being well versed in Caucasian and Oriental female anatomies as baseline, simply require some appropriate subjects of Negroid ethnicity for a well designed experimental protocol.
    Now seeking candidate; suitable subjects may apply online by submitting vital statics age, sex (yes only acceptable) and several accompanied photograph (head, torso and rear end shots) as body proof of race.
    Be aware that this study has been cleared by the SF associated Ethics Committee and the measurement apparatus has been correctly calibrated and passed all previous rigorous quality testing ;)

    Yes, especially since lots of guys would volunteer to rate various pussies for tightness!
